- * bluetty.c   Version 0.13
- *
- * Copyright (C) 2000, 2001 Greg Kroah-Hartman  <greg@kroah.com>
- * Copyright (C) 2000 Mark Douglas Corner       <mcorner@umich.edu>
- *
- * USB Bluetooth TTY driver, based on the Bluetooth Spec version 1.0B
- * 
- * (2001/11/30) Version 0.13 gkh
- *      - added locking patch from Masoodur Rahman <rmasoodu@in.ibm.com>
- *      - removed active variable, as open_count will do.
- *
- * (2001/07/09) Version 0.12 gkh
- *      - removed in_interrupt() call, as it doesn't make sense to do 
- *        that anymore.
- *
- * (2001/06/05) Version 0.11 gkh
- *      - Fixed problem with read urb status saying that we have shutdown,
- *        and that we shouldn't resubmit the urb.  Patch from unknown.
- *
- * (2001/05/28) Version 0.10 gkh
- *      - Fixed problem with using data from userspace in the bluetooth_write
- *        function as found by the CHECKER project.
- *      - Added a buffer to the write_urb_pool which reduces the number of
- *        buffers being created and destroyed for ever write.  Also cleans
- *        up the logic a bit.
- *      - Added a buffer to the control_urb_pool which fixes a memory leak
- *        when the device is removed from the system.
- *
- * (2001/05/28) Version 0.9 gkh
- *      Fixed problem with bluetooth==NULL for bluetooth_read_bulk_callback
- *      which was found by both the CHECKER project and Mikko Rahkonen.
- *
- * (08/04/2001) gb
- *      Identify version on module load.
- *
- * (2001/03/10) Version 0.8 gkh
- *      Fixed problem with not unlinking interrupt urb on device close
- *      and resubmitting the read urb on error with bluetooth struct.
- *      Thanks to Narayan Mohanram <narayan@RovingNetworks.com> for the
- *      fixes.
- *
- * (11/29/2000) Version 0.7 gkh
- *      Fixed problem with overrunning the tty flip buffer.
- *      Removed unneeded NULL pointer initialization.
- *
- * (10/05/2000) Version 0.6 gkh
- *      Fixed bug with urb->dev not being set properly, now that the usb
- *      core needs it.
- *      Got a real major id number and name.
- *
- * (08/06/2000) Version 0.5 gkh
- *      Fixed problem of not resubmitting the bulk read urb if there is
- *      an error in the callback.  Ericsson devices seem to need this.
- *
- * (07/11/2000) Version 0.4 gkh
- *      Fixed bug in disconnect for when we call tty_hangup
- *      Fixed bug in bluetooth_ctrl_msg where the bluetooth struct was not
- *      getting attached to the control urb properly.
- *      Fixed bug in bluetooth_write where we pay attention to the result
- *      of bluetooth_ctrl_msg.
- *
- * (08/03/2000) Version 0.3 gkh mdc
- *      Merged in Mark's changes to make the driver play nice with the Axis
- *      stack.
- *      Made the write bulk use an urb pool to enable larger transfers with
- *      fewer calls to the driver.
- *      Fixed off by one bug in acl pkt receive
- *      Made packet counters specific to each bluetooth device 
- *      Added checks for zero length callbacks
- *      Added buffers for int and bulk packets.  Had to do this otherwise 
- *      packet types could intermingle.
- *      Made a control urb pool for the control messages.
- *
- * (07/11/2000) Version 0.2 gkh
- *      Fixed a small bug found by Nils Faerber in the usb_bluetooth_probe 
- *      function.
- *
- * (07/09/2000) Version 0.1 gkh
- *      Initial release. Has support for sending ACL data (which is really just
- *      a HCI frame.) Raw HCI commands and HCI events are not supported.
- *      A ioctl will probably be needed for the HCI commands and events in the
- *      future. All isoch endpoints are ignored at this time also.
- *      This driver should work for all currently shipping USB Bluetooth 
- *      devices at this time :)

+- Greg Kroah-Hartman <greg@kroah.com> October 20, 2005
+
+-----------------------------------------------------------------------
+usb-serial.h Change Log comments:
+
+ (03/26/2002) gkh
+        removed the port->tty check from port_paranoia_check() due to serial
+        consoles not having a tty device assigned to them.
+
+ (12/03/2001) gkh
+        removed active from the port structure.
+        added documentation to the usb_serial_device_type structure
+
+ (10/10/2001) gkh
+        added vendor and product to serial structure.  Needed to determine device
+        owner when the device is disconnected.
+
+ (05/30/2001) gkh
+        added sem to port structure and removed port_lock
+
+ (10/05/2000) gkh
+        Added interrupt_in_endpointAddress and bulk_in_endpointAddress to help
+        fix bug with urb->dev not being set properly, now that the usb core
+        needs it.
+
+ (09/11/2000) gkh
+        Added usb_serial_debug_data function to help get rid of #DEBUG in the
+        drivers.
+
+ (08/28/2000) gkh
+        Added port_lock to port structure.
+
+ (08/08/2000) gkh
+        Added open_count to port structure.
+
+ (07/23/2000) gkh
+        Added bulk_out_endpointAddress to port structure.
+
+ (07/19/2000) gkh, pberger, and borchers
+        Modifications to allow usb-serial drivers to be modules.
+
+-----------------------------------------------------------------------
+usb-serial.c Change Log comments:
+
+ (12/10/2002) gkh
+        Split the ports off into their own struct device, and added a
+        usb-serial bus driver.
+
+ (11/19/2002) gkh
+        removed a few #ifdefs for the generic code and cleaned up the failure
+        logic in initialization.
+
+ (10/02/2002) gkh
+        moved the console code to console.c and out of this file.
+
+ (06/05/2002) gkh
+        moved location of startup() call in serial_probe() until after all
+        of the port information and endpoints are initialized.  This makes
+        things easier for some drivers.
+
+ (04/10/2002) gkh
+        added serial_read_proc function which creates a
+        /proc/tty/driver/usb-serial file.
+
+ (03/27/2002) gkh
+        Got USB serial console code working properly and merged into the main
+        version of the tree.  Thanks to Randy Dunlap for the initial version
+        of this code, and for pushing me to finish it up.
+        The USB serial console works with any usb serial driver device.
+
+ (03/21/2002) gkh
+        Moved all manipulation of port->open_count into the core.  Now the
+        individual driver's open and close functions are called only when the
+        first open() and last close() is called.  Making the drivers a bit
+        smaller and simpler.
+        Fixed a bug if a driver didn't have the owner field set.
+
+ (02/26/2002) gkh
+        Moved all locking into the main serial_* functions, instead of having
+        the individual drivers have to grab the port semaphore.  This should
+        reduce races.
+        Reworked the MOD_INC logic a bit to always increment and decrement, even
+        if the generic driver is being used.
+
+ (10/10/2001) gkh
+        usb_serial_disconnect() now sets the serial->dev pointer is to NULL to
+        help prevent child drivers from accessing the device since it is now
+        gone.
+
+ (09/13/2001) gkh
+        Moved generic driver initialize after we have registered with the USB
+        core.  Thanks to Randy Dunlap for pointing this problem out.
+
+ (07/03/2001) gkh
+        Fixed module paramater size.  Thanks to John Brockmeyer for the pointer.
+        Fixed vendor and product getting defined through the MODULE_PARM macro
+        if the Generic driver wasn't compiled in.
+        Fixed problem with generic_shutdown() not being called for drivers that
+        don't have a shutdown() function.
+
+ (06/06/2001) gkh
+        added evil hack that is needed for the prolific pl2303 device due to the
+        crazy way its endpoints are set up.
+
+ (05/30/2001) gkh
+        switched from using spinlock to a semaphore, which fixes lots of problems.
+
+ (04/08/2001) gb
+        Identify version on module load.
+
+ 2001_02_05 gkh
+        Fixed buffer overflows bug with the generic serial driver.  Thanks to
+        Todd Squires <squirest@ct0.com> for fixing this.
+
+ (01/10/2001) gkh
+        Fixed bug where the generic serial adaptor grabbed _any_ device that was
+        offered to it.
+
+ (12/12/2000) gkh
+        Removed MOD_INC and MOD_DEC from poll and disconnect functions, and
+        moved them to the serial_open and serial_close functions.
+        Also fixed bug with there not being a MOD_DEC for the generic driver
+        (thanks to Gary Brubaker for finding this.)
+
+ (11/29/2000) gkh
+        Small NULL pointer initialization cleanup which saves a bit of disk image
+
+ (11/01/2000) Adam J. Richter
+        instead of using idVendor/idProduct pairs, usb serial drivers
+        now identify their hardware interest with usb_device_id tables,
+        which they usually have anyhow for use with MODULE_DEVICE_TABLE.
+
+ (10/05/2000) gkh
+        Fixed bug with urb->dev not being set properly, now that the usb
+        core needs it.
+
+ (09/11/2000) gkh
+        Removed DEBUG #ifdefs with call to usb_serial_debug_data
+
+ (08/28/2000) gkh
+        Added port_lock to port structure.
+        Added locks for SMP safeness to generic driver
+        Fixed the ability to open a generic device's port more than once.
+
+ (07/23/2000) gkh
+        Added bulk_out_endpointAddress to port structure.
+
+ (07/19/2000) gkh, pberger, and borchers
+        Modifications to allow usb-serial drivers to be modules.
+
+ (07/03/2000) gkh
+        Added more debugging to serial_ioctl call
+
+ (06/25/2000) gkh
+        Changed generic_write_bulk_callback to not call wake_up_interruptible
+        directly, but to have port_softint do it at a safer time.
+
+ (06/23/2000) gkh
+        Cleaned up debugging statements in a quest to find UHCI timeout bug.
+
+ (05/22/2000) gkh
+        Changed the makefile, enabling the big CONFIG_USB_SERIAL_SOMTHING to be
+        removed from the individual device source files.
+
+ (05/03/2000) gkh
+        Added the Digi Acceleport driver from Al Borchers and Peter Berger.
+
+ (05/02/2000) gkh
+        Changed devfs and tty register code to work properly now. This was based on
+        the ACM driver changes by Vojtech Pavlik.
+
+ (04/27/2000) Ryan VanderBijl
+        Put calls to *_paranoia_checks into one function.
+
+ (04/23/2000) gkh
+        Fixed bug that Randy Dunlap found for Generic devices with no bulk out ports.
+        Moved when the startup code printed out the devices that are supported.
+
+ (04/19/2000) gkh
+        Added driver for ZyXEL omni.net lcd plus ISDN TA
+        Made startup info message specify which drivers were compiled in.
+
+ (04/03/2000) gkh
+        Changed the probe process to remove the module unload races.
+        Changed where the tty layer gets initialized to have devfs work nicer.
+        Added initial devfs support.
+
+ (03/26/2000) gkh
+        Split driver up into device specific pieces.
+
+ (03/19/2000) gkh
+        Fixed oops that could happen when device was removed while a program
+        was talking to the device.
+        Removed the static urbs and now all urbs are created and destroyed
+        dynamically.
+        Reworked the internal interface. Now everything is based on the
+        usb_serial_port structure instead of the larger usb_serial structure.
+        This fixes the bug that a multiport device could not have more than
+        one port open at one time.
+
+ (03/17/2000) gkh
+        Added config option for debugging messages.
+        Added patch for keyspan pda from Brian Warner.
+
+ (03/06/2000) gkh
+        Added the keyspan pda code from Brian Warner <warner@lothar.com>
+        Moved a bunch of the port specific stuff into its own structure. This
+        is in anticipation of the true multiport devices (there's a bug if you
+        try to access more than one port of any multiport device right now)
+
+ (02/21/2000) gkh
+        Made it so that any serial devices only have to specify which functions
+        they want to overload from the generic function calls (great,
+        inheritance in C, in a driver, just what I wanted...)
+        Added support for set_termios and ioctl function calls. No drivers take
+        advantage of this yet.
+        Removed the #ifdef MODULE, now there is no module specific code.
+        Cleaned up a few comments in usb-serial.h that were wrong (thanks again
+        to Miles Lott).
+        Small fix to get_free_serial.
+
+ (02/14/2000) gkh
+        Removed the Belkin and Peracom functionality from the driver due to
+        the lack of support from the vendor, and me not wanting people to
+        accidenatly buy the device, expecting it to work with Linux.
+        Added read_bulk_callback and write_bulk_callback to the type structure
+        for the needs of the FTDI and WhiteHEAT driver.
+        Changed all reverences to FTDI to FTDI_SIO at the request of Bill
+        Ryder.
+        Changed the output urb size back to the max endpoint size to make
+        the ftdi_sio driver have it easier, and due to the fact that it didn't
+        really increase the speed any.
+
+ (02/11/2000) gkh
+        Added VISOR_FUNCTION_CONSOLE to the visor startup function. This was a
+        patch from Miles Lott (milos@insync.net).
+        Fixed bug with not restoring the minor range that a device grabs, if
+        the startup function fails (thanks Miles for finding this).
+
+ (02/05/2000) gkh
+        Added initial framework for the Keyspan PDA serial converter so that
+        Brian Warner has a place to put his code.
+        Made the ezusb specific functions generic enough that different
+        devices can use them (whiteheat and keyspan_pda both need them).
+        Split out a whole bunch of structure and other stuff to a separate
+        usb-serial.h file.
+        Made the Visor connection messages a little more understandable, now
+        that Miles Lott (milos@insync.net) has gotten the Generic channel to
+        work. Also made them always show up in the log file.
+
+ (01/25/2000) gkh
+        Added initial framework for FTDI serial converter so that Bill Ryder
+        has a place to put his code.
+        Added the vendor specific info from Handspring. Now we can print out
+        informational debug messages as well as understand what is happening.
+
+ (01/23/2000) gkh
+        Fixed problem of crash when trying to open a port that didn't have a
+        device assigned to it. Made the minor node finding a little smarter,
+        now it looks to find a continuous space for the new device.
+
+ (01/21/2000) gkh
+        Fixed bug in visor_startup with patch from Miles Lott (milos@insync.net)
+        Fixed get_serial_by_minor which was all messed up for multi port
+        devices. Fixed multi port problem for generic devices. Now the number
+        of ports is determined by the number of bulk out endpoints for the
+        generic device.
+
+ (01/19/2000) gkh
+        Removed lots of cruft that was around from the old (pre urb) driver
+        interface.
+        Made the serial_table dynamic. This should save lots of memory when
+        the number of minor nodes goes up to 256.
+        Added initial support for devices that have more than one port.
+        Added more debugging comments for the Visor, and added a needed
+        set_configuration call.
+
+ (01/17/2000) gkh
+        Fixed the WhiteHEAT firmware (my processing tool had a bug)
+        and added new debug loader firmware for it.
+        Removed the put_char function as it isn't really needed.
+        Added visor startup commands as found by the Win98 dump.
+
+ (01/13/2000) gkh
+        Fixed the vendor id for the generic driver to the one I meant it to be.
+
+ (01/12/2000) gkh
+        Forget the version numbering...that's pretty useless...
+        Made the driver able to be compiled so that the user can select which
+        converter they want to use. This allows people who only want the Visor
+        support to not pay the memory size price of the WhiteHEAT.
+        Fixed bug where the generic driver (idVendor=0000 and idProduct=0000)
+        grabbed the root hub. Not good.
+
+ version 0.4.0 (01/10/2000) gkh
+        Added whiteheat.h containing the firmware for the ConnectTech WhiteHEAT
+        device. Added startup function to allow firmware to be downloaded to
+        a device if it needs to be.
+        Added firmware download logic to the WhiteHEAT device.
+        Started to add #defines to split up the different drivers for potential
+        configuration option.
+
+ version 0.3.1 (12/30/99) gkh
+      Fixed problems with urb for bulk out.
+      Added initial support for multiple sets of endpoints. This enables
+      the Handspring Visor to be attached successfully. Only the first
+      bulk in / bulk out endpoint pair is being used right now.
+
+ version 0.3.0 (12/27/99) gkh
+        Added initial support for the Handspring Visor based on a patch from
+        Miles Lott (milos@sneety.insync.net)
+        Cleaned up the code a bunch and converted over to using urbs only.
+
+ version 0.2.3 (12/21/99) gkh
+        Added initial support for the Connect Tech WhiteHEAT converter.
+        Incremented the number of ports in expectation of getting the
+        WhiteHEAT to work properly (4 ports per connection).
+        Added notification on insertion and removal of what port the
+        device is/was connected to (and what kind of device it was).
+
+ version 0.2.2 (12/16/99) gkh
+        Changed major number to the new allocated number. We're legal now!
+
+ version 0.2.1 (12/14/99) gkh
+        Fixed bug that happens when device node is opened when there isn't a
+        device attached to it. Thanks to marek@webdesign.no for noticing this.
+
+ version 0.2.0 (11/10/99) gkh
+        Split up internals to make it easier to add different types of serial
+        converters to the code.
+        Added a "generic" driver that gets it's vendor and product id
+        from when the module is loaded. Thanks to David E. Nelson (dnelson@jump.net)
+        for the idea and sample code (from the usb scanner driver.)
+        Cleared up any licensing questions by releasing it under the GNU GPL.
+
+ version 0.1.2 (10/25/99) gkh
+        Fixed bug in detecting device.
+
+ version 0.1.1 (10/05/99) gkh
+        Changed the major number to not conflict with anything else.
+
+ version 0.1 (09/28/99) gkh
+        Can recognize the two different devices and start up a read from
+        device when asked to. Writes also work. No control signals yet, this
+        all is vendor specific data (i.e. no spec), also no control for
+        different baud rates or other bit settings.
+        Currently we are using the same devid as the acm driver. This needs
+        to change.

+visor.c Change Log comments:
+
+ (06/03/2003) Judd Montgomery <judd at jpilot.org>
+     Added support for module parameter options for untested/unknown
+     devices.
+
+ (03/09/2003) gkh
+        Added support for the Sony Clie NZ90V device.  Thanks to Martin Brachtl
+        <brachtl@redgrep.cz> for the information.
+
+ (03/05/2003) gkh
+        Think Treo support is now working.
+
+ (04/03/2002) gkh
+        Added support for the Sony OS 4.1 devices.  Thanks to Hiroyuki ARAKI
+        <hiro@zob.ne.jp> for the information.
+
+ (03/27/2002) gkh
+        Removed assumptions that port->tty was always valid (is not true
+        for usb serial console devices.)
+
+ (03/23/2002) gkh
+        Added support for the Palm i705 device, thanks to Thomas Riemer
+        <tom@netmech.com> for the information.
+
+ (03/21/2002) gkh
+        Added support for the Palm m130 device, thanks to Udo Eisenbarth
+        <udo.eisenbarth@web.de> for the information.
+
+ (02/27/2002) gkh
+        Reworked the urb handling logic.  We have no more pool, but dynamically
+        allocate the urb and the transfer buffer on the fly.  In testing this
+        does not incure any measurable overhead.  This also relies on the fact
+        that we have proper reference counting logic for urbs.
+
+ (02/21/2002) SilaS
+  Added initial support for the Palm m515 devices.
+
+ (02/14/2002) gkh
+        Added support for the Clie S-360 device.
+
+ (12/18/2001) gkh
+        Added better Clie support for 3.5 devices.  Thanks to Geoffrey Levand
+        for the patch.
+
+ (11/11/2001) gkh
+        Added support for the m125 devices, and added check to prevent oopses
+        for Clié devices that lie about the number of ports they have.
+
+ (08/30/2001) gkh
+        Added support for the Clie devices, both the 3.5 and 4.0 os versions.
+        Many thanks to Daniel Burke, and Bryan Payne for helping with this.
+
+ (08/23/2001) gkh
+        fixed a few potential bugs pointed out by Oliver Neukum.
+
+ (05/30/2001) gkh
+        switched from using spinlock to a semaphore, which fixes lots of problems.
+
+ (05/28/2000) gkh
+        Added initial support for the Palm m500 and Palm m505 devices.
+
+ (04/08/2001) gb
+        Identify version on module load.
+
+ (01/21/2000) gkh
+        Added write_room and chars_in_buffer, as they were previously using the
+        generic driver versions which is all wrong now that we are using an urb
+        pool.  Thanks to Wolfgang Grandegger for pointing this out to me.
+        Removed count assignment in the write function, which was not needed anymore
+        either.  Thanks to Al Borchers for pointing this out.
+
+ (12/12/2000) gkh
+        Moved MOD_DEC to end of visor_close to be nicer, as the final write
+        message can sleep.
+
+ (11/12/2000) gkh
+        Fixed bug with data being dropped on the floor by forcing tty->low_latency
+        to be on.  Hopefully this fixes the OHCI issue!
+
+ (11/01/2000) Adam J. Richter
+        usb_device_id table support
+
+ (10/05/2000) gkh
+        Fixed bug with urb->dev not being set properly, now that the usb
+        core needs it.
+
+ (09/11/2000) gkh
+        Got rid of always calling kmalloc for every urb we wrote out to the
+        device.
+        Added visor_read_callback so we can keep track of bytes in and out for
+        those people who like to know the speed of their device.
+        Removed DEBUG #ifdefs with call to usb_serial_debug_data
+
+ (09/06/2000) gkh
+        Fixed oops in visor_exit.  Need to uncomment usb_unlink_urb call _after_
+        the host controller drivers set urb->dev = NULL when the urb is finished.
+
+ (08/28/2000) gkh
+        Added locks for SMP safeness.
+
+ (08/08/2000) gkh
+        Fixed endian problem in visor_startup.
+        Fixed MOD_INC and MOD_DEC logic and the ability to open a port more
+        than once.
+
+ (07/23/2000) gkh
+        Added pool of write urbs to speed up transfers to the visor.
+
+ (07/19/2000) gkh
+        Added module_init and module_exit functions to handle the fact that this
+        driver is a loadable module now.
+
+ (07/03/2000) gkh
+        Added visor_set_ioctl and visor_set_termios functions (they don't do much
+        of anything, but are good for debugging.)
+
+ (06/25/2000) gkh
+        Fixed bug in visor_unthrottle that should help with the disconnect in PPP
+        bug that people have been reporting.
+
+ (06/23/2000) gkh
+        Cleaned up debugging statements in a quest to find UHCI timeout bug.
+
+ (04/27/2000) Ryan VanderBijl
+        Fixed memory leak in visor_close
+
+ (03/26/2000) gkh
+        Split driver up into device specific pieces.
+
+-----------------------------------------------------------------------
+pl2303.c Change Log comments:
+
+ 2002_Mar_26 gkh
+        allowed driver to work properly if there is no tty assigned to a port
+        (this happens for serial console devices.)
+
+ 2001_Oct_06 gkh
+        Added RTS and DTR line control.  Thanks to joe@bndlg.de for parts of it.
+
+ 2001_Sep_19 gkh
+        Added break support.
+
+ 2001_Aug_30 gkh
+        fixed oops in write_bulk_callback.
+
+ 2001_Aug_28 gkh
+        reworked buffer logic to be like other usb-serial drivers.  Hopefully
+        removing some reported problems.
+
+ 2001_Jun_06 gkh
+        finished porting to 2.4 format.
+

+        Warning! This version leaks memory like crazy!
+
+ 0.2 (01/30/2000) greg kroah-hartman
+        Milestone 1 release.
+        Device is found by USB subsystem, enumerated, fimware is downloaded
+        and the descriptors are printed to the debug log, config is set, and
+        green light starts to blink. Open port works, and data can be sent
+        and received at the default settings of the UART. Loopback connector
+        and debug log confirms this.
+
+ 0.1 (01/23/2000) greg kroah-hartman
+        Initial release to help IO Networks try to set up their test system.
+        Edgeport4 is recognized, firmware is downloaded, config is set so
+        device blinks green light every 3 sec. Port is bound, but opening,
+        closing, and sending data do not work properly.

- *      Device is found by USB subsystem, enumerated, fimware is downloaded
- *      and the descriptors are printed to the debug log, config is set, and
- *      green light starts to blink. Open port works, and data can be sent
- *      and received at the default settings of the UART. Loopback connector
- *      and debug log confirms this.
- * 
- * 0.1 (01/23/2000) greg kroah-hartman
- *      Initial release to help IO Networks try to set up their test system. 
- *      Edgeport4 is recognized, firmware is downloaded, config is set so 
- *      device blinks green light every 3 sec. Port is bound, but opening,
- *      closing, and sending data do not work properly.

  *
  * See Documentation/usb/usb-serial.txt for more information on using this driver
  *
- * (12/10/2002) gkh
- *      Split the ports off into their own struct device, and added a
- *      usb-serial bus driver.
- *
- * (11/19/2002) gkh
- *      removed a few #ifdefs for the generic code and cleaned up the failure
- *      logic in initialization.
- *
- * (10/02/2002) gkh
- *      moved the console code to console.c and out of this file.
- *
- * (06/05/2002) gkh
- *      moved location of startup() call in serial_probe() until after all
- *      of the port information and endpoints are initialized.  This makes
- *      things easier for some drivers.
- *
- * (04/10/2002) gkh
- *      added serial_read_proc function which creates a
- *      /proc/tty/driver/usb-serial file.
- *
- * (03/27/2002) gkh
- *      Got USB serial console code working properly and merged into the main
- *      version of the tree.  Thanks to Randy Dunlap for the initial version
- *      of this code, and for pushing me to finish it up.
- *      The USB serial console works with any usb serial driver device.
- *
- * (03/21/2002) gkh
- *      Moved all manipulation of port->open_count into the core.  Now the
- *      individual driver's open and close functions are called only when the
- *      first open() and last close() is called.  Making the drivers a bit
- *      smaller and simpler.
- *      Fixed a bug if a driver didn't have the owner field set.
- *
- * (02/26/2002) gkh
- *      Moved all locking into the main serial_* functions, instead of having 
- *      the individual drivers have to grab the port semaphore.  This should
- *      reduce races.
- *      Reworked the MOD_INC logic a bit to always increment and decrement, even
- *      if the generic driver is being used.
- *
- * (10/10/2001) gkh
- *      usb_serial_disconnect() now sets the serial->dev pointer is to NULL to
- *      help prevent child drivers from accessing the device since it is now
- *      gone.
- *
- * (09/13/2001) gkh
- *      Moved generic driver initialize after we have registered with the USB
- *      core.  Thanks to Randy Dunlap for pointing this problem out.
- *
- * (07/03/2001) gkh
- *      Fixed module paramater size.  Thanks to John Brockmeyer for the pointer.
- *      Fixed vendor and product getting defined through the MODULE_PARM macro
- *      if the Generic driver wasn't compiled in.
- *      Fixed problem with generic_shutdown() not being called for drivers that
- *      don't have a shutdown() function.
- *
- * (06/06/2001) gkh
- *      added evil hack that is needed for the prolific pl2303 device due to the
- *      crazy way its endpoints are set up.
- *
- * (05/30/2001) gkh
- *      switched from using spinlock to a semaphore, which fixes lots of problems.
- *
- * (04/08/2001) gb
- *      Identify version on module load.
- *
- * 2001_02_05 gkh
- *      Fixed buffer overflows bug with the generic serial driver.  Thanks to
- *      Todd Squires <squirest@ct0.com> for fixing this.
- *
- * (01/10/2001) gkh
- *      Fixed bug where the generic serial adaptor grabbed _any_ device that was
- *      offered to it.
- *
- * (12/12/2000) gkh
- *      Removed MOD_INC and MOD_DEC from poll and disconnect functions, and
- *      moved them to the serial_open and serial_close functions.
- *      Also fixed bug with there not being a MOD_DEC for the generic driver
- *      (thanks to Gary Brubaker for finding this.)
- *
- * (11/29/2000) gkh
- *      Small NULL pointer initialization cleanup which saves a bit of disk image
- *
- * (11/01/2000) Adam J. Richter
- *      instead of using idVendor/idProduct pairs, usb serial drivers
- *      now identify their hardware interest with usb_device_id tables,
- *      which they usually have anyhow for use with MODULE_DEVICE_TABLE.
- *
- * (10/05/2000) gkh
- *      Fixed bug with urb->dev not being set properly, now that the usb
- *      core needs it.
- * 
- * (09/11/2000) gkh
- *      Removed DEBUG #ifdefs with call to usb_serial_debug_data
- *
- * (08/28/2000) gkh
- *      Added port_lock to port structure.
- *      Added locks for SMP safeness to generic driver
- *      Fixed the ability to open a generic device's port more than once.
- *
- * (07/23/2000) gkh
- *      Added bulk_out_endpointAddress to port structure.
- *
- * (07/19/2000) gkh, pberger, and borchers
- *      Modifications to allow usb-serial drivers to be modules.
- *
- * (07/03/2000) gkh
- *      Added more debugging to serial_ioctl call
- * 
- * (06/25/2000) gkh
- *      Changed generic_write_bulk_callback to not call wake_up_interruptible
- *      directly, but to have port_softint do it at a safer time.
- *
- * (06/23/2000) gkh
- *      Cleaned up debugging statements in a quest to find UHCI timeout bug.
- *
- * (05/22/2000) gkh
- *      Changed the makefile, enabling the big CONFIG_USB_SERIAL_SOMTHING to be 
- *      removed from the individual device source files.
- *
- * (05/03/2000) gkh
- *      Added the Digi Acceleport driver from Al Borchers and Peter Berger.
- * 
- * (05/02/2000) gkh
- *      Changed devfs and tty register code to work properly now. This was based on
- *      the ACM driver changes by Vojtech Pavlik.
- *
- * (04/27/2000) Ryan VanderBijl
- *      Put calls to *_paranoia_checks into one function.
- * 
- * (04/23/2000) gkh
- *      Fixed bug that Randy Dunlap found for Generic devices with no bulk out ports.
- *      Moved when the startup code printed out the devices that are supported.
- *
- * (04/19/2000) gkh
- *      Added driver for ZyXEL omni.net lcd plus ISDN TA
- *      Made startup info message specify which drivers were compiled in.
- *
- * (04/03/2000) gkh
- *      Changed the probe process to remove the module unload races.
- *      Changed where the tty layer gets initialized to have devfs work nicer.
- *      Added initial devfs support.
- *
- * (03/26/2000) gkh
- *      Split driver up into device specific pieces.
- * 
- * (03/19/2000) gkh
- *      Fixed oops that could happen when device was removed while a program
- *      was talking to the device.
- *      Removed the static urbs and now all urbs are created and destroyed
- *      dynamically.
- *      Reworked the internal interface. Now everything is based on the 
- *      usb_serial_port structure instead of the larger usb_serial structure.
- *      This fixes the bug that a multiport device could not have more than
- *      one port open at one time.
- *
- * (03/17/2000) gkh
- *      Added config option for debugging messages.
- *      Added patch for keyspan pda from Brian Warner.
- *
- * (03/06/2000) gkh
- *      Added the keyspan pda code from Brian Warner <warner@lothar.com>
- *      Moved a bunch of the port specific stuff into its own structure. This
- *      is in anticipation of the true multiport devices (there's a bug if you
- *      try to access more than one port of any multiport device right now)
- *
- * (02/21/2000) gkh
- *      Made it so that any serial devices only have to specify which functions
- *      they want to overload from the generic function calls (great, 
- *      inheritance in C, in a driver, just what I wanted...)
- *      Added support for set_termios and ioctl function calls. No drivers take
- *      advantage of this yet.
- *      Removed the #ifdef MODULE, now there is no module specific code.
- *      Cleaned up a few comments in usb-serial.h that were wrong (thanks again
- *      to Miles Lott).
- *      Small fix to get_free_serial.
- *
- * (02/14/2000) gkh
- *      Removed the Belkin and Peracom functionality from the driver due to
- *      the lack of support from the vendor, and me not wanting people to 
- *      accidenatly buy the device, expecting it to work with Linux.
- *      Added read_bulk_callback and write_bulk_callback to the type structure
- *      for the needs of the FTDI and WhiteHEAT driver.
- *      Changed all reverences to FTDI to FTDI_SIO at the request of Bill
- *      Ryder.
- *      Changed the output urb size back to the max endpoint size to make
- *      the ftdi_sio driver have it easier, and due to the fact that it didn't
- *      really increase the speed any.
- *
- * (02/11/2000) gkh
- *      Added VISOR_FUNCTION_CONSOLE to the visor startup function. This was a
- *      patch from Miles Lott (milos@insync.net).
- *      Fixed bug with not restoring the minor range that a device grabs, if
- *      the startup function fails (thanks Miles for finding this).
- *
- * (02/05/2000) gkh
- *      Added initial framework for the Keyspan PDA serial converter so that
- *      Brian Warner has a place to put his code.
- *      Made the ezusb specific functions generic enough that different
- *      devices can use them (whiteheat and keyspan_pda both need them).
- *      Split out a whole bunch of structure and other stuff to a separate
- *      usb-serial.h file.
- *      Made the Visor connection messages a little more understandable, now
- *      that Miles Lott (milos@insync.net) has gotten the Generic channel to
- *      work. Also made them always show up in the log file.
- * 
- * (01/25/2000) gkh
- *      Added initial framework for FTDI serial converter so that Bill Ryder
- *      has a place to put his code.
- *      Added the vendor specific info from Handspring. Now we can print out
- *      informational debug messages as well as understand what is happening.
- *
- * (01/23/2000) gkh
- *      Fixed problem of crash when trying to open a port that didn't have a
- *      device assigned to it. Made the minor node finding a little smarter,
- *      now it looks to find a continuous space for the new device.
- *
- * (01/21/2000) gkh
- *      Fixed bug in visor_startup with patch from Miles Lott (milos@insync.net)
- *      Fixed get_serial_by_minor which was all messed up for multi port 
- *      devices. Fixed multi port problem for generic devices. Now the number
- *      of ports is determined by the number of bulk out endpoints for the
- *      generic device.
- *
- * (01/19/2000) gkh
- *      Removed lots of cruft that was around from the old (pre urb) driver 
- *      interface.
- *      Made the serial_table dynamic. This should save lots of memory when
- *      the number of minor nodes goes up to 256.
- *      Added initial support for devices that have more than one port. 
- *      Added more debugging comments for the Visor, and added a needed 
- *      set_configuration call.
- *
- * (01/17/2000) gkh
- *      Fixed the WhiteHEAT firmware (my processing tool had a bug)
- *      and added new debug loader firmware for it.
- *      Removed the put_char function as it isn't really needed.
- *      Added visor startup commands as found by the Win98 dump.
- * 
- * (01/13/2000) gkh
- *      Fixed the vendor id for the generic driver to the one I meant it to be.
- *
- * (01/12/2000) gkh
- *      Forget the version numbering...that's pretty useless...
- *      Made the driver able to be compiled so that the user can select which
- *      converter they want to use. This allows people who only want the Visor
- *      support to not pay the memory size price of the WhiteHEAT.
- *      Fixed bug where the generic driver (idVendor=0000 and idProduct=0000)
- *      grabbed the root hub. Not good.
- * 
- * version 0.4.0 (01/10/2000) gkh
- *      Added whiteheat.h containing the firmware for the ConnectTech WhiteHEAT
- *      device. Added startup function to allow firmware to be downloaded to
- *      a device if it needs to be.
- *      Added firmware download logic to the WhiteHEAT device.
- *      Started to add #defines to split up the different drivers for potential
- *      configuration option.
- *      
- * version 0.3.1 (12/30/99) gkh
- *      Fixed problems with urb for bulk out.
- *      Added initial support for multiple sets of endpoints. This enables
- *      the Handspring Visor to be attached successfully. Only the first
- *      bulk in / bulk out endpoint pair is being used right now.
- *
- * version 0.3.0 (12/27/99) gkh
- *      Added initial support for the Handspring Visor based on a patch from
- *      Miles Lott (milos@sneety.insync.net)
- *      Cleaned up the code a bunch and converted over to using urbs only.
- *
- * version 0.2.3 (12/21/99) gkh
- *      Added initial support for the Connect Tech WhiteHEAT converter.
- *      Incremented the number of ports in expectation of getting the
- *      WhiteHEAT to work properly (4 ports per connection).
- *      Added notification on insertion and removal of what port the
- *      device is/was connected to (and what kind of device it was).
- *
- * version 0.2.2 (12/16/99) gkh
- *      Changed major number to the new allocated number. We're legal now!
- *
- * version 0.2.1 (12/14/99) gkh
- *      Fixed bug that happens when device node is opened when there isn't a
- *      device attached to it. Thanks to marek@webdesign.no for noticing this.
- *
- * version 0.2.0 (11/10/99) gkh
- *      Split up internals to make it easier to add different types of serial 
- *      converters to the code.
- *      Added a "generic" driver that gets it's vendor and product id
- *      from when the module is loaded. Thanks to David E. Nelson (dnelson@jump.net)
- *      for the idea and sample code (from the usb scanner driver.)
- *      Cleared up any licensing questions by releasing it under the GNU GPL.
- *
- * version 0.1.2 (10/25/99) gkh
- *      Fixed bug in detecting device.
- *
- * version 0.1.1 (10/05/99) gkh
- *      Changed the major number to not conflict with anything else.
- *
- * version 0.1 (09/28/99) gkh
- *      Can recognize the two different devices and start up a read from
- *      device when asked to. Writes also work. No control signals yet, this
- *      all is vendor specific data (i.e. no spec), also no control for
- *      different baud rates or other bit settings.
- *      Currently we are using the same devid as the acm driver. This needs
- *      to change.

- *      allocate the urb and the transfer buffer on the fly.  In testing this

- *      for the patch.
- *
- * (11/11/2001) gkh

- *      Added write_room and chars_in_buffer, as they were previously using the
- *      generic driver versions which is all wrong now that we are using an urb
- *      pool.  Thanks to Wolfgang Grandegger for pointing this out to me.
- *      Removed count assignment in the write function, which was not needed anymore
- *      either.  Thanks to Al Borchers for pointing this out.
- *
- * (12/12/2000) gkh
- *      Moved MOD_DEC to end of visor_close to be nicer, as the final write 
- *      message can sleep.
- * 
- * (11/12/2000) gkh
- *      Fixed bug with data being dropped on the floor by forcing tty->low_latency
- *      to be on.  Hopefully this fixes the OHCI issue!

- *      usb_device_id table support

- *      core needs it.
- * 
- * (09/11/2000) gkh
- *      Got rid of always calling kmalloc for every urb we wrote out to the
- *      device.
- *      Added visor_read_callback so we can keep track of bytes in and out for
- *      those people who like to know the speed of their device.
- *      Removed DEBUG #ifdefs with call to usb_serial_debug_data
- *
- * (09/06/2000) gkh
- *      Fixed oops in visor_exit.  Need to uncomment usb_unlink_urb call _after_
- *      the host controller drivers set urb->dev = NULL when the urb is finished.
- *
- * (08/28/2000) gkh
- *      Added locks for SMP safeness.
- *
- * (08/08/2000) gkh
- *      Fixed endian problem in visor_startup.
- *      Fixed MOD_INC and MOD_DEC logic and the ability to open a port more 
- *      than once.
- * 
- * (07/23/2000) gkh
- *      Added pool of write urbs to speed up transfers to the visor.
- * 
- * (07/19/2000) gkh
- *      Added module_init and module_exit functions to handle the fact that this
- *      driver is a loadable module now.
- *
- * (07/03/2000) gkh
- *      Added visor_set_ioctl and visor_set_termios functions (they don't do much
- *      of anything, but are good for debugging.)
- * 
- * (06/25/2000) gkh
- *      Fixed bug in visor_unthrottle that should help with the disconnect in PPP
- *      bug that people have been reporting.
- *
- * (06/23/2000) gkh
- *      Cleaned up debugging statements in a quest to find UHCI timeout bug.
