-What:   USB driver API moves to EXPORT_SYMBOL_GPL
-When:   February 2008
-Files:  include/linux/usb.h, drivers/usb/core/driver.c
-Why:    The USB subsystem has changed a lot over time, and it has been
-        possible to create userspace USB drivers using usbfs/libusb/gadgetfs
-        that operate as fast as the USB bus allows.  Because of this, the USB
-        subsystem will not be allowing closed source kernel drivers to
-        register with it, after this grace period is over.  If anyone needs
-        any help in converting their closed source drivers over to use the

-        linux-usb-devel@lists.sourceforge.net mailing list, and the developers

+ *                      - Transfer size fix for Samsung CD-ROMs, thanks to
+ *                        "Ville Hallik" <ville.hallik@mail.ee>.
+ *                      - other minor stuff.
+ *
+ * 4.52  Jan 19, 1999  -- Jens Axboe <axboe@image.dk>
+ *                      - Detect DVD-ROM/RAM drives
+ *
+ * 4.53  Feb 22, 1999   - Include other model Samsung and one Goldstar
+ *                         drive in transfer size limit.
+ *                      - Fix the I/O error when doing eject without a medium
+ *                         loaded on some drives.
+ *                      - CDROMREADMODE2 is now implemented through
+ *                         CDROMREADRAW, since many drives don't support
+ *                         MODE2 (even though ATAPI 2.6 says they must).
+ *                      - Added ignore parameter to ide-cd (as a module), eg
+ *                              insmod ide-cd ignore='hda hdb'
+ *                         Useful when using ide-cd in conjunction with
+ *                         ide-scsi. TODO: non-modular way of doing the
+ *                         same.
+ *
+ * 4.54  Aug 5, 1999    - Support for MMC2 class commands through the generic
+ *                        packet interface to cdrom.c.
+ *                      - Unified audio ioctl support, most of it.
+ *                      - cleaned up various deprecated verify_area().
+ *                      - Added ide_cdrom_packet() as the interface for
+ *                        the Uniform generic_packet().
+ *                      - bunch of other stuff, will fill in logs later.
+ *                      - report 1 slot for non-changers, like the other
+ *                        cd-rom drivers. don't report select disc for
+ *                        non-changers as well.
+ *                      - mask out audio playing, if the device can't do it.
+ *
+ * 4.55  Sep 1, 1999    - Eliminated the rest of the audio ioctls, except
+ *                        for CDROMREADTOC[ENTRY|HEADER]. Some of the drivers
+ *                        use this independently of the actual audio handling.
+ *                        They will disappear later when I get the time to
+ *                        do it cleanly.
+ *                      - Minimize the TOC reading - only do it when we
+ *                        know a media change has occurred.
+ *                      - Moved all the CDROMREADx ioctls to the Uniform layer.
+ *                      - Heiko Eißfeldt <heiko@colossus.escape.de> supplied
+ *                        some fixes for CDI.
+ *                      - CD-ROM leaving door locked fix from Andries
+ *                        Brouwer <Andries.Brouwer@cwi.nl>
+ *                      - Erik Andersen <andersen@xmission.com> unified
+ *                        commands across the various drivers and how
+ *                        sense errors are handled.
+ *
+ * 4.56  Sep 12, 1999   - Removed changer support - it is now in the
+ *                        Uniform layer.
+ *                      - Added partition based multisession handling.
+ *                      - Mode sense and mode select moved to the
+ *                        Uniform layer.
+ *                      - Fixed a problem with WPI CDS-32X drive - it
+ *                        failed the capabilities
+ *
+ * 4.57  Apr 7, 2000    - Fixed sense reporting.
+ *                      - Fixed possible oops in ide_cdrom_get_last_session()
+ *                      - Fix locking mania and make ide_cdrom_reset relock
+ *                      - Stop spewing errors to log when magicdev polls with
+ *                        TEST_UNIT_READY on some drives.
+ *                      - Various fixes from Tobias Ringstrom:
+ *                        tray if it was locked prior to the reset.
+ *                        - cdrom_read_capacity returns one frame too little.

+/*
+ * Many thanks to Lode Leroy <Lode.Leroy@www.ibase.be>, who tested so many
+ * ALPHA patches to this driver on an EASYSTOR LS-120 ATAPI floppy drive.
+ *
+ * Ver 0.1   Oct 17 96   Initial test version, mostly based on ide-tape.c.
+ * Ver 0.2   Oct 31 96   Minor changes.
+ * Ver 0.3   Dec  2 96   Fixed error recovery bug.
+ * Ver 0.4   Jan 26 97   Add support for the HDIO_GETGEO ioctl.
+ * Ver 0.5   Feb 21 97   Add partitions support.
+ *                       Use the minimum of the LBA and CHS capacities.
+ *                       Avoid hwgroup->rq == NULL on the last irq.
+ *                       Fix potential null dereferencing with DEBUG_LOG.
+ * Ver 0.8   Dec  7 97   Increase irq timeout from 10 to 50 seconds.
+ *                       Add media write-protect detection.
+ *                       Issue START command only if TEST UNIT READY fails.
+ *                       Add work-around for IOMEGA ZIP revision 21.D.
+ *                       Remove idefloppy_get_capabilities().
+ * Ver 0.9   Jul  4 99   Fix a bug which might have caused the number of
+ *                        bytes requested on each interrupt to be zero.
+ *                        Thanks to <shanos@es.co.nz> for pointing this out.
+ * Ver 0.9.sv Jan 6 01   Sam Varshavchik <mrsam@courier-mta.com>
+ *                       Implement low level formatting.  Reimplemented
+ *                       IDEFLOPPY_CAPABILITIES_PAGE, since we need the srfp
+ *                       bit.  My LS-120 drive barfs on
+ *                       IDEFLOPPY_CAPABILITIES_PAGE, but maybe it's just me.
+ *                       Compromise by not reporting a failure to get this
+ *                       mode page.  Implemented four IOCTLs in order to
+ *                       implement formatting.  IOCTls begin with 0x4600,
+ *                       0x46 is 'F' as in Format.
+ *            Jan 9 01   Userland option to select format verify.
+ *                       Added PC_SUPPRESS_ERROR flag - some idefloppy drives
+ *                       do not implement IDEFLOPPY_CAPABILITIES_PAGE, and
+ *                       return a sense error.  Suppress error reporting in
+ *                       this particular case in order to avoid spurious
+ *                       errors in syslog.  The culprit is
+ *                       idefloppy_get_capability_page(), so move it to
+ *                       idefloppy_begin_format() so that it's not used
+ *                       unless absolutely necessary.
+ *                       If drive does not support format progress indication
+ *                       monitor the dsc bit in the status register.
+ *                       Also, O_NDELAY on open will allow the device to be
+ *                       opened without a disk available.  This can be used to
+ *                       open an unformatted disk, or get the device capacity.
+ * Ver 0.91  Dec 11 99   Added IOMEGA Clik! drive support by
+ *                 <paul@paulbristow.net>
+ * Ver 0.92  Oct 22 00   Paul Bristow became official maintainer for this
+ *                         driver.  Included Powerbook internal zip kludge.
+ * Ver 0.93  Oct 24 00   Fixed bugs for Clik! drive
+ *                        no disk on insert and disk change now works
+ * Ver 0.94  Oct 27 00   Tidied up to remove strstr(Clik) everywhere
+ * Ver 0.95  Nov  7 00   Brought across to kernel 2.4
+ * Ver 0.96  Jan  7 01   Actually in line with release version of 2.4.0
+ *                       including set_bit patch from Rusty Russell
+ * Ver 0.97  Jul 22 01   Merge 0.91-0.96 onto 0.9.sv for ac series
+ * Ver 0.97.sv Aug 3 01  Backported from 2.4.7-ac3
+ * Ver 0.98  Oct 26 01   Split idefloppy_transfer_pc into two pieces to
+ *                        fix a lost interrupt problem. It appears the busy
+ *                        bit was being deasserted by my IOMEGA ATAPI ZIP 100
+ *                        drive before the drive was actually ready.
+ * Ver 0.98a Oct 29 01   Expose delay value so we can play.
+ * Ver 0.99  Feb 24 02   Remove duplicate code, modify clik! detection code
+ *                        to support new PocketZip drives

+                       Linux USB Printer Gadget Driver
+                                 06/04/2007
+
+              Copyright (C) 2007 Craig W. Nadler <craig@nadler.us>
+
+
+
+GENERAL
+=======
+
+This driver may be used if you are writing printer firmware using Linux as
+the embedded OS. This driver has nothing to do with using a printer with
+your Linux host system.
+
+You will need a USB device controller and a Linux driver for it that accepts
+a gadget / "device class" driver using the Linux USB Gadget API. After the
+USB device controller driver is loaded then load the printer gadget driver.
+This will present a printer interface to the USB Host that your USB Device
+port is connected to.
+
+This driver is structured for printer firmware that runs in user mode. The
+user mode printer firmware will read and write data from the kernel mode
+printer gadget driver using a device file. The printer returns a printer status
+byte when the USB HOST sends a device request to get the printer status.  The
+user space firmware can read or write this status byte using a device file
+/dev/g_printer . Both blocking and non-blocking read/write calls are supported.
+
+
+
+
+HOWTO USE THIS DRIVER
+=====================
+
+To load the USB device controller driver and the printer gadget driver. The
+following example uses the Netchip 2280 USB device controller driver:
+
+modprobe net2280
+modprobe g_printer
+
+
+The follow command line parameter can be used when loading the printer gadget
+(ex: modprobe g_printer idVendor=0x0525 idProduct=0xa4a8 ):
+
+idVendor - This is the Vendor ID used in the device descriptor. The default is
+        the Netchip vendor id 0x0525. YOU MUST CHANGE TO YOUR OWN VENDOR ID
+        BEFORE RELEASING A PRODUCT. If you plan to release a product and don't
+        already have a Vendor ID please see www.usb.org for details on how to
+        get one.
+
+idProduct - This is the Product ID used in the device descriptor. The default
+        is 0xa4a8, you should change this to an ID that's not used by any of
+        your other USB products if you have any. It would be a good idea to
+        start numbering your products starting with say 0x0001.
+
+bcdDevice - This is the version number of your product. It would be a good idea
+        to put your firmware version here.
+
+iManufacturer - A string containing the name of the Vendor.
+
+iProduct - A string containing the Product Name.
+
+iSerialNum - A string containing the Serial Number. This should be changed for
+        each unit of your product.
+
+iPNPstring -  The PNP ID string used for this printer. You will want to set
+        either on the command line or hard code the PNP ID string used for
+        your printer product.
+
+qlen - The number of 8k buffers to use per endpoint. The default is 10, you
+        should tune this for your product. You may also want to tune the
+        size of each buffer for your product.
+
+
+
+
+USING THE EXAMPLE CODE
+======================
+
+This example code talks to stdout, instead of a print engine.
+
+To compile the test code below:
+
+1) save it to a file called prn_example.c
+2) compile the code with the follow command:
+         gcc prn_example.c -o prn_example
+
+
+
+To read printer data from the host to stdout:
+
+        # prn_example -read_data
+
+
+To write printer data from a file (data_file) to the host:
+
+        # cat data_file | prn_example -write_data
+
+
+To get the current printer status for the gadget driver:
+
+        # prn_example -get_status
+
+        Printer status is:
+             Printer is NOT Selected
+             Paper is Out
+             Printer OK
+
+
+To set printer to Selected/On-line:
+
+        # prn_example -selected
+
+
+To set printer to Not Selected/Off-line:
+
+        # prn_example -not_selected
+
+
+To set paper status to paper out:
+
+        # prn_example -paper_out
+
+
+To set paper status to paper loaded:
+
+        # prn_example -paper_loaded
+
+
+To set error status to printer OK:
+
+        # prn_example -no_error
+
+
+To set error status to ERROR:
+
+        # prn_example -error
+
+

+Infinity Usb Unlimited Readme
+-----------------------------
+
+Hi all,
+
+
+This module provide a serial interface to use your
+IUU unit in phoenix mode. Loading this module will
+bring a ttyUSB[0-x] interface. This driver must be
+used by your favorite application to pilot the IUU
+
+This driver is still in beta stage, so bugs can
+occur and your system may freeze. As far I now,
+I never had any problem with it, but I'm not a real
+guru, so don't blame me if your system is unstable
+
+You can plug more than one IUU. Every unit will
+have his own device file(/dev/ttyUSB0,/dev/ttyUSB1,...)
+
+
+
+How to tune the reader speed ?
+
+ A few parameters can be used at load time
+ To use parameters, just unload the module if it is
+ already loaded and use modprobe iuu_phoenix param=value.
+ In case of prebuilt module, use the command
+ insmod iuu_phoenix param=value.
+
+ Example:
+
+ modprobe iuu_phoenix clockmode=3
+
+ The parameters are:
+
+ parm:           clockmode:1=3Mhz579,2=3Mhz680,3=6Mhz (int)
+ parm:           boost:overclock boost percent 100 to 500 (int)
+ parm:           cdmode:Card detect mode 0=none, 1=CD, 2=!CD, 3=DSR, 4=!DSR, 5=CTS, 6=!CTS, 7=RING, 8=!RING (int)
+ parm:           xmas:xmas color enabled or not (bool)
+ parm:           debug:Debug enabled or not (bool)
+
+-  clockmode will provide 3 different base settings commonly adopted by
+   different software:
+        1. 3Mhz579
+        2. 3Mhz680
+        3. 6Mhz
+
+-  boost provide a way to overclock the reader ( my favorite :-)  )
+   For example to have best performance than a simple clockmode=3, try this:
+
+      modprobe boost=195
+
+   This will put the reader in a base of 3Mhz579 but boosted a 195 % !
+   the real clock will be now : 6979050 Hz ( 6Mhz979 ) and will increase
+   the speed to a score 10 to 20% better than the simple clockmode=3 !!!
+
+
+-  cdmode permit to setup the signal used to inform the userland ( ioctl answer )
+   if the card is present or not. Eight signals are possible.
+
+-  xmas is completely useless except for your eyes. This is one of my friend who was
+   so sad to have a nice device like the iuu without seeing all color range available.
+   So I have added this option to permit him to see a lot of color ( each activity change the color
+   and the frequency randomly )
+
+-  debug will produce a lot of debugging messages...
+
+
+ Last notes:
+
+ Don't worry about the serial settings, the serial emulation
+ is an abstraction, so use any speed or parity setting will
+ work. ( This will not change anything ).Later I will perhaps
+ use this settings to deduce de boost but is that feature
+ really necessary ?
+ The autodetect feature used is the serial CD. If that doesn't
+ work for your software, disable detection mechanism in it.
+
+
+ Have fun !
+

- * Many thanks to Lode Leroy <Lode.Leroy@www.ibase.be>, who tested so many
- * ALPHA patches to this driver on an EASYSTOR LS-120 ATAPI floppy drive.
- *
- * Ver 0.1   Oct 17 96   Initial test version, mostly based on ide-tape.c.
- * Ver 0.2   Oct 31 96   Minor changes.
- * Ver 0.3   Dec  2 96   Fixed error recovery bug.
- * Ver 0.4   Jan 26 97   Add support for the HDIO_GETGEO ioctl.
- * Ver 0.5   Feb 21 97   Add partitions support.
- *                       Use the minimum of the LBA and CHS capacities.
- *                       Avoid hwgroup->rq == NULL on the last irq.
- *                       Fix potential null dereferencing with DEBUG_LOG.
- * Ver 0.8   Dec  7 97   Increase irq timeout from 10 to 50 seconds.
- *                       Add media write-protect detection.
- *                       Issue START command only if TEST UNIT READY fails.
- *                       Add work-around for IOMEGA ZIP revision 21.D.
- *                       Remove idefloppy_get_capabilities().
- * Ver 0.9   Jul  4 99   Fix a bug which might have caused the number of
- *                        bytes requested on each interrupt to be zero.
- *                        Thanks to <shanos@es.co.nz> for pointing this out.
- * Ver 0.9.sv Jan 6 01   Sam Varshavchik <mrsam@courier-mta.com>
- *                       Implement low level formatting.  Reimplemented
- *                       IDEFLOPPY_CAPABILITIES_PAGE, since we need the srfp
- *                       bit.  My LS-120 drive barfs on
- *                       IDEFLOPPY_CAPABILITIES_PAGE, but maybe it's just me.
- *                       Compromise by not reporting a failure to get this
- *                       mode page.  Implemented four IOCTLs in order to
- *                       implement formatting.  IOCTls begin with 0x4600,
- *                       0x46 is 'F' as in Format.
- *            Jan 9 01   Userland option to select format verify.
- *                       Added PC_SUPPRESS_ERROR flag - some idefloppy drives
- *                       do not implement IDEFLOPPY_CAPABILITIES_PAGE, and
- *                       return a sense error.  Suppress error reporting in
- *                       this particular case in order to avoid spurious
- *                       errors in syslog.  The culprit is
- *                       idefloppy_get_capability_page(), so move it to
- *                       idefloppy_begin_format() so that it's not used
- *                       unless absolutely necessary.
- *                       If drive does not support format progress indication
- *                       monitor the dsc bit in the status register.
- *                       Also, O_NDELAY on open will allow the device to be
- *                       opened without a disk available.  This can be used to
- *                       open an unformatted disk, or get the device capacity.
- * Ver 0.91  Dec 11 99   Added IOMEGA Clik! drive support by 
- *                 <paul@paulbristow.net>
- * Ver 0.92  Oct 22 00   Paul Bristow became official maintainer for this 
- *                         driver.  Included Powerbook internal zip kludge.
- * Ver 0.93  Oct 24 00   Fixed bugs for Clik! drive
- *                        no disk on insert and disk change now works
- * Ver 0.94  Oct 27 00   Tidied up to remove strstr(Clik) everywhere
- * Ver 0.95  Nov  7 00   Brought across to kernel 2.4
- * Ver 0.96  Jan  7 01   Actually in line with release version of 2.4.0
- *                       including set_bit patch from Rusty Russell
- * Ver 0.97  Jul 22 01   Merge 0.91-0.96 onto 0.9.sv for ac series
- * Ver 0.97.sv Aug 3 01  Backported from 2.4.7-ac3
- * Ver 0.98  Oct 26 01   Split idefloppy_transfer_pc into two pieces to
- *                        fix a lost interrupt problem. It appears the busy

- *                        drive before the drive was actually ready.
- * Ver 0.98a Oct 29 01   Expose delay value so we can play.
- * Ver 0.99  Feb 24 02   Remove duplicate code, modify clik! detection code

- * (21/Jul/2004) Ian Abbott
- *      Incorporated Steven Turner's code to add support for the FT2232C chip.
- *      The prelimilary port to the 2.6 kernel was by Rus V. Brushkoff.  I have
- *      fixed a couple of things.
- *
- * (27/May/2004) Ian Abbott
- *      Improved throttling code, mostly stolen from the WhiteHEAT driver.
- *
- * (26/Mar/2004) Jan Capek
- *      Added PID's for ICD-U20/ICD-U40 - incircuit PIC debuggers from CCS Inc.
- *
- * (09/Feb/2004) Ian Abbott
- *      Changed full name of USB-UIRT device to avoid "/" character.
- *      Added FTDI's alternate PID (0x6006) for FT232/245 devices.
- *      Added PID for "ELV USB Module UO100" from Stefan Frings.
- *
- * (21/Oct/2003) Ian Abbott
- *      Renamed some VID/PID macros for Matrix Orbital and Perle Systems
- *      devices.  Removed Matrix Orbital and Perle Systems devices from the
- *      8U232AM device table, but left them in the FT232BM table, as they are
- *      known to use only FT232BM.
- *
- * (17/Oct/2003) Scott Allen
- *      Added vid/pid for Perle Systems UltraPort USB serial converters
- *
- * (21/Sep/2003) Ian Abbott
- *      Added VID/PID for Omnidirectional Control Technology US101 USB to
- *      RS-232 adapter (also rebadged as Dick Smith Electronics XH6381).
- *      VID/PID supplied by Donald Gordon.
- *
- * (19/Aug/2003) Ian Abbott
- *      Freed urb's transfer buffer in write bulk callback.
- *      Omitted some paranoid checks in write bulk callback that don't matter.
- *      Scheduled work in write bulk callback regardless of port's open count.
- *
- * (05/Aug/2003) Ian Abbott
- *      Added VID/PID for ID TECH IDT1221U USB to RS-232 adapter.
- *      VID/PID provided by Steve Briggs.
- *
- * (23/Jul/2003) Ian Abbott
- *      Added PIDs for CrystalFontz 547, 633, 631, 635, 640 and 640 from
- *      Wayne Wylupski.
- *
- * (10/Jul/2003) David Glance
- *      Added PID for DSS-20 SyncStation cradle for Sony-Ericsson P800.
- *
- * (27/Jun/2003) Ian Abbott
- *      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.  I nicked this
- *      from Greg KH's Visor driver.
- *
- * (23/Jun/2003) Ian Abbott
- *      Reduced flip buffer pushes and corrected a data length test in
- *      ftdi_read_bulk_callback.
- *      Defererence pointers after any paranoid checks, not before.
- *
- * (21/Jun/2003) Erik Nygren
- *      Added support for Home Electronics Tira-1 IR transceiver using FT232BM chip.
- *      See <http://www.home-electro.com/tira1.htm>.  Only operates properly
- *      at 100000 and RTS-CTS, so set custom divisor mode on startup.
- *      Also force the Tira-1 and USB-UIRT to only use their custom baud rates.
- *
- * (18/Jun/2003) Ian Abbott
- *      Added Device ID of the USB relais from Rudolf Gugler (backported from
- *      Philipp Gühring's patch for 2.5.x kernel).
- *      Moved read transfer buffer reallocation into startup function.
- *      Free existing write urb and transfer buffer in startup function.
- *      Only use urbs in write urb pool that were successfully allocated.
- *      Moved some constant macros out of functions.
- *      Minor whitespace and comment changes.
- *
- * (12/Jun/2003) David Norwood
- *      Added support for USB-UIRT IR transceiver using 8U232AM chip.
- *      See <http://home.earthlink.net/~jrhees/USBUIRT/index.htm>.  Only
- *      operates properly at 312500, so set custom divisor mode on startup.
- *
- * (12/Jun/2003) Ian Abbott
- *      Added Sealevel SeaLINK+ 210x, 220x, 240x, 280x vid/pids from Tuan Hoang
- *      - I've eliminated some that don't seem to exist!
- *      Added Home Electronics Tira-1 IR transceiver pid from Chris Horn
- *      Some whitespace/coding-style cleanups
- *
- * (11/Jun/2003) Ian Abbott

- * (24/Feb/2003) Richard Shooter
- *      Increase read buffer size to improve read speeds at higher baud rates
- *      (specifically tested with up to 1Mb/sec at 1.5M baud)
- *
- * (23/Feb/2003) John Wilkins
- *      Added Xon/xoff flow control (activating support in the ftdi device)
- *      Added vid/pid for Videonetworks/Homechoice (UK ISP)
- *
- * (23/Feb/2003) Bill Ryder
- *      Added matrix orb device vid/pids from Wayne Wylupski
- *
- * (19/Feb/2003) Ian Abbott
- *      For TIOCSSERIAL, set alt_speed to 0 when ASYNC_SPD_MASK value has
- *      changed to something other than ASYNC_SPD_HI, ASYNC_SPD_VHI,
- *      ASYNC_SPD_SHI or ASYNC_SPD_WARP.  Also, unless ASYNC_SPD_CUST is in
- *      force, don't bother changing baud rate when custom_divisor has changed.
- *
- * (18/Feb/2003) Ian Abbott
- *      Fixed TIOCMGET handling to include state of DTR and RTS, the state
- *      of which are now saved by set_dtr() and set_rts().
- *      Fixed improper storage class for buf in set_dtr() and set_rts().
- *      Added FT232BM chip type and support for its extra baud rates (compared
- *      to FT8U232AM).
- *      Took account of special case divisor values for highest baud rates of
- *      FT8U232AM and FT232BM.
- *      For TIOCSSERIAL, forced alt_speed to 0 when ASYNC_SPD_CUST kludge used,
- *      as previous alt_speed setting is now stale.
- *      Moved startup code common between the startup routines for the
- *      different chip types into a common subroutine.
- *
- * (17/Feb/2003) Bill Ryder
- *      Added write urb buffer pool on a per device basis
- *      Added more checking for open file on callbacks (fixed OOPS)
- *      Added CrystalFontz 632 and 634 PIDs
- *         (thanx to CrystalFontz for the sample devices - they flushed out
- *           some driver bugs)
- *      Minor debugging message changes
- *      Added throttle, unthrottle and chars_in_buffer functions
- *      Fixed FTDI_SIO (the original device) bug
- *      Fixed some shutdown handling
- *
- *
- *
- *
- * (07/Jun/2002) Kuba Ober
- *      Changed FTDI_SIO_BASE_BAUD_TO_DIVISOR macro into ftdi_baud_to_divisor
- *      function. It was getting too complex.
- *      Fix the divisor calculation logic which was setting divisor of 0.125
- *      instead of 0.5 for fractional parts of divisor equal to 5/8, 6/8, 7/8.
- *      Also make it bump up the divisor to next integer in case of 7/8 - it's
- *      a better approximation.
- *
- * (25/Jul/2002) Bill Ryder inserted Dmitri's TIOCMIWAIT patch
- *      Not tested by me but it doesn't break anything I use.
- *
- * (04/Jan/2002) Kuba Ober
- *      Implemented 38400 baudrate kludge, where it can be substituted with other
- *        values. That's the only way to set custom baudrates.
- *      Implemented TIOCSSERIAL, TIOCGSERIAL ioctl's so that setserial is happy.
- *      FIXME: both baudrate things should eventually go to usbserial.c as other
- *        devices may need that functionality too. Actually, it can probably be
- *        merged in serial.c somehow - too many drivers repeat this code over
- *        and over.
- *      Fixed baudrate forgetfulness - open() used to reset baudrate to 9600 every time.
- *      Divisors for baudrates are calculated by a macro.
- *      Small code cleanups. Ugly whitespace changes for Plato's sake only ;-].
- *
- * (04/Nov/2001) Bill Ryder
- *      Fixed bug in read_bulk_callback where incorrect urb buffer was used.
- *      Cleaned up write offset calculation
- *      Added write_room since default values can be incorrect for sio
- *      Changed write_bulk_callback to use same queue_task as other drivers
- *        (the previous version caused panics)
- *      Removed port iteration code since the device only has one I/O port and it
- *        was wrong anyway.
- *
- * (31/May/2001) gkh
- *      Switched from using spinlock to a semaphore, which fixes lots of problems.
- *
- * (23/May/2001)   Bill Ryder
- *      Added runtime debug patch (thanx Tyson D Sawyer).
- *      Cleaned up comments for 8U232
- *      Added parity, framing and overrun error handling
- *      Added receive break handling.
- *
- * (04/08/2001) gb
- *      Identify version on module load.
- *
- * (18/March/2001) Bill Ryder
- *      (Not released)
- *      Added send break handling. (requires kernel patch too)
- *      Fixed 8U232AM hardware RTS/CTS etc status reporting.
- *      Added flipbuf fix copied from generic device
- *
- * (12/3/2000) Bill Ryder
- *      Added support for 8U232AM device.
- *      Moved PID and VIDs into header file only.
- *      Turned on low-latency for the tty (device will do high baudrates)
- *      Added shutdown routine to close files when device removed.
- *      More debug and error message cleanups.
- *
- * (11/13/2000) Bill Ryder
- *      Added spinlock protected open code and close code.
- *      Multiple opens work (sort of - see webpage mentioned above).
- *      Cleaned up comments. Removed multiple PID/VID definitions.
- *      Factorised cts/dtr code
- *      Made use of __FUNCTION__ in dbg's
- *
- * (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
- *      Removed DEBUG #ifdefs with call to usb_serial_debug_data
- *
- * (07/19/2000) gkh
- *      Added module_init and module_exit functions to handle the fact that this
- *      driver is a loadable module now.
- *
- * (04/04/2000) Bill Ryder
- *      Fixed bugs in TCGET/TCSET ioctls (by removing them - they are
- *        handled elsewhere in the tty io driver chain).
- *
- * (03/30/2000) Bill Ryder
- *      Implemented lots of ioctls
- *      Fixed a race condition in write
- *      Changed some dbg's to errs
- *
- * (03/26/2000) gkh
- *      Split driver up into device specific pieces.
+ * Change entries from 2004 and earlier can be found in versions of this
+ * file in kernel versions prior to the 2.6.24 release.
