7 * USB Bluetooth TTY driver, based on the Bluetooth Spec version 1.0B
8 *
9 * (2001/11/30) Version 0.13 gkh
10 * - added locking patch from Masoodur Rahman <rmasoodu@in.ibm.com>
11 * - removed active variable, as open_count will do.
12 *
13 * (2001/07/09) Version 0.12 gkh
14 * - removed in_interrupt() call, as it doesn't make sense to do
15 * that anymore.
16 *
17 * (2001/06/05) Version 0.11 gkh
18 * - Fixed problem with read urb status saying that we have shutdown,
19 * and that we shouldn't resubmit the urb. Patch from unknown.
20 *
21 * (2001/05/28) Version 0.10 gkh
22 * - Fixed problem with using data from userspace in the bluetooth_write
23 * function as found by the CHECKER project.
24 * - Added a buffer to the write_urb_pool which reduces the number of
25 * buffers being created and destroyed for ever write. Also cleans
26 * up the logic a bit.
27 * - Added a buffer to the control_urb_pool which fixes a memory leak
28 * when the device is removed from the system.
29 *
30 * (2001/05/28) Version 0.9 gkh
31 * Fixed problem with bluetooth==NULL for bluetooth_read_bulk_callback
32 * which was found by both the CHECKER project and Mikko Rahkonen.
33 *
34 * (08/04/2001) gb
35 * Identify version on module load.
36 *
37 * (2001/03/10) Version 0.8 gkh
38 * Fixed problem with not unlinking interrupt urb on device close
39 * and resubmitting the read urb on error with bluetooth struct.
40 * Thanks to Narayan Mohanram <narayan@RovingNetworks.com> for the
41 * fixes.
42 *
43 * (11/29/2000) Version 0.7 gkh
44 * Fixed problem with overrunning the tty flip buffer.
45 * Removed unneeded NULL pointer initialization.
46 *
47 * (10/05/2000) Version 0.6 gkh
48 * Fixed bug with urb->dev not being set properly, now that the usb
49 * core needs it.
50 * Got a real major id number and name.
51 *
52 * (08/06/2000) Version 0.5 gkh
53 * Fixed problem of not resubmitting the bulk read urb if there is
54 * an error in the callback. Ericsson devices seem to need this.
55 *
56 * (07/11/2000) Version 0.4 gkh
57 * Fixed bug in disconnect for when we call tty_hangup
58 * Fixed bug in bluetooth_ctrl_msg where the bluetooth struct was not
59 * getting attached to the control urb properly.
60 * Fixed bug in bluetooth_write where we pay attention to the result
61 * of bluetooth_ctrl_msg.
62 *
63 * (08/03/2000) Version 0.3 gkh mdc
64 * Merged in Mark's changes to make the driver play nice with the Axis
65 * stack.
66 * Made the write bulk use an urb pool to enable larger transfers with
67 * fewer calls to the driver.
68 * Fixed off by one bug in acl pkt receive
69 * Made packet counters specific to each bluetooth device
70 * Added checks for zero length callbacks
71 * Added buffers for int and bulk packets. Had to do this otherwise
72 * packet types could intermingle.
73 * Made a control urb pool for the control messages.
74 *
75 * (07/11/2000) Version 0.2 gkh
76 * Fixed a small bug found by Nils Faerber in the usb_bluetooth_probe
77 * function.
78 *
79 * (07/09/2000) Version 0.1 gkh
80 * Initial release. Has support for sending ACL data (which is really just
81 * a HCI frame.) Raw HCI commands and HCI events are not supported.
82 * A ioctl will probably be needed for the HCI commands and events in the
83 * future. All isoch endpoints are ignored at this time also.
84 * This driver should work for all currently shipping USB Bluetooth
85 * devices at this time :)

72 USB devices (like keyboards and network adapters) can wake up
73 their parent hub. That wakeup cascades up the USB tree, and
74 could wake the system from states like suspend-to-RAM.

1This is the contents of some of the drivers/usb/serial/ files that had old
2changelog comments. They were quite old, and out of date, and we don't keep
3them anymore, so I've put them here, away from the source files, in case
4people still care to see them.

8-----------------------------------------------------------------------
9usb-serial.h Change Log comments:
10
11 (03/26/2002) gkh
12 removed the port->tty check from port_paranoia_check() due to serial
13 consoles not having a tty device assigned to them.
14
15 (12/03/2001) gkh
16 removed active from the port structure.
17 added documentation to the usb_serial_device_type structure
18
19 (10/10/2001) gkh
20 added vendor and product to serial structure. Needed to determine device
21 owner when the device is disconnected.
22
23 (05/30/2001) gkh
24 added sem to port structure and removed port_lock
25
26 (10/05/2000) gkh
27 Added interrupt_in_endpointAddress and bulk_in_endpointAddress to help
28 fix bug with urb->dev not being set properly, now that the usb core
29 needs it.
30
31 (09/11/2000) gkh
32 Added usb_serial_debug_data function to help get rid of #DEBUG in the
33 drivers.
34
35 (08/28/2000) gkh
36 Added port_lock to port structure.
37
38 (08/08/2000) gkh
39 Added open_count to port structure.
40
41 (07/23/2000) gkh
42 Added bulk_out_endpointAddress to port structure.
43
44 (07/19/2000) gkh, pberger, and borchers
45 Modifications to allow usb-serial drivers to be modules.
46
47-----------------------------------------------------------------------
48usb-serial.c Change Log comments:
49
50 (12/10/2002) gkh
51 Split the ports off into their own struct device, and added a
52 usb-serial bus driver.
53
54 (11/19/2002) gkh
55 removed a few #ifdefs for the generic code and cleaned up the failure
56 logic in initialization.
57
58 (10/02/2002) gkh
59 moved the console code to console.c and out of this file.
60
61 (06/05/2002) gkh
62 moved location of startup() call in serial_probe() until after all
63 of the port information and endpoints are initialized. This makes
64 things easier for some drivers.
65
66 (04/10/2002) gkh
67 added serial_read_proc function which creates a
68 /proc/tty/driver/usb-serial file.
69
70 (03/27/2002) gkh
71 Got USB serial console code working properly and merged into the main
72 version of the tree. Thanks to Randy Dunlap for the initial version
73 of this code, and for pushing me to finish it up.
74 The USB serial console works with any usb serial driver device.
75
76 (03/21/2002) gkh
77 Moved all manipulation of port->open_count into the core. Now the
78 individual driver's open and close functions are called only when the
79 first open() and last close() is called. Making the drivers a bit
80 smaller and simpler.
81 Fixed a bug if a driver didn't have the owner field set.
82
83 (02/26/2002) gkh
84 Moved all locking into the main serial_* functions, instead of having
85 the individual drivers have to grab the port semaphore. This should
86 reduce races.
87 Reworked the MOD_INC logic a bit to always increment and decrement, even
88 if the generic driver is being used.
89
90 (10/10/2001) gkh
91 usb_serial_disconnect() now sets the serial->dev pointer is to NULL to
92 help prevent child drivers from accessing the device since it is now
93 gone.
94
95 (09/13/2001) gkh
96 Moved generic driver initialize after we have registered with the USB
97 core. Thanks to Randy Dunlap for pointing this problem out.
98
99 (07/03/2001) gkh
100 Fixed module paramater size. Thanks to John Brockmeyer for the pointer.
101 Fixed vendor and product getting defined through the MODULE_PARM macro
102 if the Generic driver wasn't compiled in.
103 Fixed problem with generic_shutdown() not being called for drivers that
104 don't have a shutdown() function.
105
106 (06/06/2001) gkh
107 added evil hack that is needed for the prolific pl2303 device due to the
108 crazy way its endpoints are set up.
109
110 (05/30/2001) gkh
111 switched from using spinlock to a semaphore, which fixes lots of problems.
112
113 (04/08/2001) gb
114 Identify version on module load.
115
116 2001_02_05 gkh
117 Fixed buffer overflows bug with the generic serial driver. Thanks to
118 Todd Squires <squirest@ct0.com> for fixing this.
119
120 (01/10/2001) gkh
121 Fixed bug where the generic serial adaptor grabbed _any_ device that was
122 offered to it.
123
124 (12/12/2000) gkh
125 Removed MOD_INC and MOD_DEC from poll and disconnect functions, and
126 moved them to the serial_open and serial_close functions.
127 Also fixed bug with there not being a MOD_DEC for the generic driver
128 (thanks to Gary Brubaker for finding this.)
129
130 (11/29/2000) gkh
131 Small NULL pointer initialization cleanup which saves a bit of disk image
132
133 (11/01/2000) Adam J. Richter
134 instead of using idVendor/idProduct pairs, usb serial drivers
135 now identify their hardware interest with usb_device_id tables,
136 which they usually have anyhow for use with MODULE_DEVICE_TABLE.
137
138 (10/05/2000) gkh
139 Fixed bug with urb->dev not being set properly, now that the usb
140 core needs it.
141
142 (09/11/2000) gkh
143 Removed DEBUG #ifdefs with call to usb_serial_debug_data
144
145 (08/28/2000) gkh
146 Added port_lock to port structure.
147 Added locks for SMP safeness to generic driver
148 Fixed the ability to open a generic device's port more than once.
149
150 (07/23/2000) gkh
151 Added bulk_out_endpointAddress to port structure.
152
153 (07/19/2000) gkh, pberger, and borchers
154 Modifications to allow usb-serial drivers to be modules.
155
156 (07/03/2000) gkh
157 Added more debugging to serial_ioctl call
158
159 (06/25/2000) gkh
160 Changed generic_write_bulk_callback to not call wake_up_interruptible
161 directly, but to have port_softint do it at a safer time.
162
163 (06/23/2000) gkh
164 Cleaned up debugging statements in a quest to find UHCI timeout bug.
165
166 (05/22/2000) gkh
167 Changed the makefile, enabling the big CONFIG_USB_SERIAL_SOMTHING to be
168 removed from the individual device source files.
169
170 (05/03/2000) gkh
171 Added the Digi Acceleport driver from Al Borchers and Peter Berger.
172
173 (05/02/2000) gkh
174 Changed devfs and tty register code to work properly now. This was based on
175 the ACM driver changes by Vojtech Pavlik.
176
177 (04/27/2000) Ryan VanderBijl
178 Put calls to *_paranoia_checks into one function.
179
180 (04/23/2000) gkh
181 Fixed bug that Randy Dunlap found for Generic devices with no bulk out ports.
182 Moved when the startup code printed out the devices that are supported.
183
184 (04/19/2000) gkh
185 Added driver for ZyXEL omni.net lcd plus ISDN TA
186 Made startup info message specify which drivers were compiled in.
187
188 (04/03/2000) gkh
189 Changed the probe process to remove the module unload races.
190 Changed where the tty layer gets initialized to have devfs work nicer.
191 Added initial devfs support.
192
193 (03/26/2000) gkh
194 Split driver up into device specific pieces.
195
196 (03/19/2000) gkh
197 Fixed oops that could happen when device was removed while a program
198 was talking to the device.
199 Removed the static urbs and now all urbs are created and destroyed
200 dynamically.
201 Reworked the internal interface. Now everything is based on the
202 usb_serial_port structure instead of the larger usb_serial structure.
203 This fixes the bug that a multiport device could not have more than
204 one port open at one time.
205
206 (03/17/2000) gkh
207 Added config option for debugging messages.
208 Added patch for keyspan pda from Brian Warner.
209
210 (03/06/2000) gkh
211 Added the keyspan pda code from Brian Warner <warner@lothar.com>
212 Moved a bunch of the port specific stuff into its own structure. This
213 is in anticipation of the true multiport devices (there's a bug if you
214 try to access more than one port of any multiport device right now)
215
216 (02/21/2000) gkh
217 Made it so that any serial devices only have to specify which functions
218 they want to overload from the generic function calls (great,
219 inheritance in C, in a driver, just what I wanted...)
220 Added support for set_termios and ioctl function calls. No drivers take
221 advantage of this yet.
222 Removed the #ifdef MODULE, now there is no module specific code.
223 Cleaned up a few comments in usb-serial.h that were wrong (thanks again
224 to Miles Lott).
225 Small fix to get_free_serial.
226
227 (02/14/2000) gkh
228 Removed the Belkin and Peracom functionality from the driver due to
229 the lack of support from the vendor, and me not wanting people to
230 accidenatly buy the device, expecting it to work with Linux.
231 Added read_bulk_callback and write_bulk_callback to the type structure
232 for the needs of the FTDI and WhiteHEAT driver.
233 Changed all reverences to FTDI to FTDI_SIO at the request of Bill
234 Ryder.
235 Changed the output urb size back to the max endpoint size to make
236 the ftdi_sio driver have it easier, and due to the fact that it didn't
237 really increase the speed any.
238
239 (02/11/2000) gkh
240 Added VISOR_FUNCTION_CONSOLE to the visor startup function. This was a
241 patch from Miles Lott (milos@insync.net).
242 Fixed bug with not restoring the minor range that a device grabs, if
243 the startup function fails (thanks Miles for finding this).
244
245 (02/05/2000) gkh
246 Added initial framework for the Keyspan PDA serial converter so that
247 Brian Warner has a place to put his code.
248 Made the ezusb specific functions generic enough that different
249 devices can use them (whiteheat and keyspan_pda both need them).
250 Split out a whole bunch of structure and other stuff to a separate
251 usb-serial.h file.
252 Made the Visor connection messages a little more understandable, now
253 that Miles Lott (milos@insync.net) has gotten the Generic channel to
254 work. Also made them always show up in the log file.
255
256 (01/25/2000) gkh
257 Added initial framework for FTDI serial converter so that Bill Ryder
258 has a place to put his code.
259 Added the vendor specific info from Handspring. Now we can print out
260 informational debug messages as well as understand what is happening.
261
262 (01/23/2000) gkh
263 Fixed problem of crash when trying to open a port that didn't have a
264 device assigned to it. Made the minor node finding a little smarter,
265 now it looks to find a continuous space for the new device.
266
267 (01/21/2000) gkh
268 Fixed bug in visor_startup with patch from Miles Lott (milos@insync.net)
269 Fixed get_serial_by_minor which was all messed up for multi port
270 devices. Fixed multi port problem for generic devices. Now the number
271 of ports is determined by the number of bulk out endpoints for the
272 generic device.
273
274 (01/19/2000) gkh
275 Removed lots of cruft that was around from the old (pre urb) driver
276 interface.
277 Made the serial_table dynamic. This should save lots of memory when
278 the number of minor nodes goes up to 256.
279 Added initial support for devices that have more than one port.
280 Added more debugging comments for the Visor, and added a needed
281 set_configuration call.
282
283 (01/17/2000) gkh
284 Fixed the WhiteHEAT firmware (my processing tool had a bug)
285 and added new debug loader firmware for it.
286 Removed the put_char function as it isn't really needed.
287 Added visor startup commands as found by the Win98 dump.
288
289 (01/13/2000) gkh
290 Fixed the vendor id for the generic driver to the one I meant it to be.
291
292 (01/12/2000) gkh
293 Forget the version numbering...that's pretty useless...
294 Made the driver able to be compiled so that the user can select which
295 converter they want to use. This allows people who only want the Visor
296 support to not pay the memory size price of the WhiteHEAT.
297 Fixed bug where the generic driver (idVendor=0000 and idProduct=0000)
298 grabbed the root hub. Not good.
299
300 version 0.4.0 (01/10/2000) gkh
301 Added whiteheat.h containing the firmware for the ConnectTech WhiteHEAT
302 device. Added startup function to allow firmware to be downloaded to
303 a device if it needs to be.
304 Added firmware download logic to the WhiteHEAT device.
305 Started to add #defines to split up the different drivers for potential
306 configuration option.
307
308 version 0.3.1 (12/30/99) gkh
309 Fixed problems with urb for bulk out.
310 Added initial support for multiple sets of endpoints. This enables
311 the Handspring Visor to be attached successfully. Only the first
312 bulk in / bulk out endpoint pair is being used right now.
313
314 version 0.3.0 (12/27/99) gkh
315 Added initial support for the Handspring Visor based on a patch from
316 Miles Lott (milos@sneety.insync.net)
317 Cleaned up the code a bunch and converted over to using urbs only.
318
319 version 0.2.3 (12/21/99) gkh
320 Added initial support for the Connect Tech WhiteHEAT converter.
321 Incremented the number of ports in expectation of getting the
322 WhiteHEAT to work properly (4 ports per connection).
323 Added notification on insertion and removal of what port the
324 device is/was connected to (and what kind of device it was).
325
326 version 0.2.2 (12/16/99) gkh
327 Changed major number to the new allocated number. We're legal now!
328
329 version 0.2.1 (12/14/99) gkh
330 Fixed bug that happens when device node is opened when there isn't a
331 device attached to it. Thanks to marek@webdesign.no for noticing this.
332
333 version 0.2.0 (11/10/99) gkh
334 Split up internals to make it easier to add different types of serial
335 converters to the code.
336 Added a "generic" driver that gets it's vendor and product id
337 from when the module is loaded. Thanks to David E. Nelson (dnelson@jump.net)
338 for the idea and sample code (from the usb scanner driver.)
339 Cleared up any licensing questions by releasing it under the GNU GPL.
340
341 version 0.1.2 (10/25/99) gkh
342 Fixed bug in detecting device.
343
344 version 0.1.1 (10/05/99) gkh
345 Changed the major number to not conflict with anything else.
346
347 version 0.1 (09/28/99) gkh
348 Can recognize the two different devices and start up a read from
349 device when asked to. Writes also work. No control signals yet, this
350 all is vendor specific data (i.e. no spec), also no control for
351 different baud rates or other bit settings.
352 Currently we are using the same devid as the acm driver. This needs
353 to change.
354
355-----------------------------------------------------------------------
356visor.c Change Log comments:
357
358 (06/03/2003) Judd Montgomery <judd at jpilot.org>
359 Added support for module parameter options for untested/unknown
360 devices.
361
362 (03/09/2003) gkh
363 Added support for the Sony Clie NZ90V device. Thanks to Martin Brachtl
364 <brachtl@redgrep.cz> for the information.
365
366 (03/05/2003) gkh
367 Think Treo support is now working.
368
369 (04/03/2002) gkh
370 Added support for the Sony OS 4.1 devices. Thanks to Hiroyuki ARAKI
371 <hiro@zob.ne.jp> for the information.
372
373 (03/27/2002) gkh
374 Removed assumptions that port->tty was always valid (is not true
375 for usb serial console devices.)
376
377 (03/23/2002) gkh
378 Added support for the Palm i705 device, thanks to Thomas Riemer
379 <tom@netmech.com> for the information.
380
381 (03/21/2002) gkh
382 Added support for the Palm m130 device, thanks to Udo Eisenbarth
383 <udo.eisenbarth@web.de> for the information.
384
385 (02/27/2002) gkh
386 Reworked the urb handling logic. We have no more pool, but dynamically
387 allocate the urb and the transfer buffer on the fly. In testing this
388 does not incure any measurable overhead. This also relies on the fact
389 that we have proper reference counting logic for urbs.
390
391 (02/21/2002) SilaS
392 Added initial support for the Palm m515 devices.
393
394 (02/14/2002) gkh
395 Added support for the Clie S-360 device.
396
397 (12/18/2001) gkh
398 Added better Clie support for 3.5 devices. Thanks to Geoffrey Levand
399 for the patch.
400
401 (11/11/2001) gkh
402 Added support for the m125 devices, and added check to prevent oopses
403 for Clié devices that lie about the number of ports they have.
404
405 (08/30/2001) gkh
406 Added support for the Clie devices, both the 3.5 and 4.0 os versions.
407 Many thanks to Daniel Burke, and Bryan Payne for helping with this.
408
409 (08/23/2001) gkh
410 fixed a few potential bugs pointed out by Oliver Neukum.
411
412 (05/30/2001) gkh
413 switched from using spinlock to a semaphore, which fixes lots of problems.
414
415 (05/28/2000) gkh
416 Added initial support for the Palm m500 and Palm m505 devices.
417
418 (04/08/2001) gb
419 Identify version on module load.
420
421 (01/21/2000) gkh
422 Added write_room and chars_in_buffer, as they were previously using the
423 generic driver versions which is all wrong now that we are using an urb
424 pool. Thanks to Wolfgang Grandegger for pointing this out to me.
425 Removed count assignment in the write function, which was not needed anymore
426 either. Thanks to Al Borchers for pointing this out.
427
428 (12/12/2000) gkh
429 Moved MOD_DEC to end of visor_close to be nicer, as the final write
430 message can sleep.
431
432 (11/12/2000) gkh
433 Fixed bug with data being dropped on the floor by forcing tty->low_latency
434 to be on. Hopefully this fixes the OHCI issue!
435
436 (11/01/2000) Adam J. Richter
437 usb_device_id table support
438
439 (10/05/2000) gkh
440 Fixed bug with urb->dev not being set properly, now that the usb
441 core needs it.
442
443 (09/11/2000) gkh
444 Got rid of always calling kmalloc for every urb we wrote out to the
445 device.
446 Added visor_read_callback so we can keep track of bytes in and out for
447 those people who like to know the speed of their device.
448 Removed DEBUG #ifdefs with call to usb_serial_debug_data
449

718 Device is found by USB subsystem, enumerated, fimware is downloaded
719 and the descriptors are printed to the debug log, config is set, and
720 green light starts to blink. Open port works, and data can be sent
721 and received at the default settings of the UART. Loopback connector
722 and debug log confirms this.

237 * Device is found by USB subsystem, enumerated, fimware is downloaded
238 * and the descriptors are printed to the debug log, config is set, and
239 * green light starts to blink. Open port works, and data can be sent
240 * and received at the default settings of the UART. Loopback connector
241 * and debug log confirms this.
242 *
243 * 0.1 (01/23/2000) greg kroah-hartman
244 * Initial release to help IO Networks try to set up their test system.
245 * Edgeport4 is recognized, firmware is downloaded, config is set so
246 * device blinks green light every 3 sec. Port is bound, but opening,
247 * closing, and sending data do not work properly.

16 * 16 *
17 * (12/10/2002) gkh
18 * Split the ports off into their own struct device, and added a
19 * usb-serial bus driver.
20 *
21 * (11/19/2002) gkh
22 * removed a few #ifdefs for the generic code and cleaned up the failure
23 * logic in initialization.
24 *
25 * (10/02/2002) gkh
26 * moved the console code to console.c and out of this file.
27 *
28 * (06/05/2002) gkh
29 * moved location of startup() call in serial_probe() until after all
30 * of the port information and endpoints are initialized. This makes
31 * things easier for some drivers.
32 *
33 * (04/10/2002) gkh
34 * added serial_read_proc function which creates a
35 * /proc/tty/driver/usb-serial file.
36 *
37 * (03/27/2002) gkh
38 * Got USB serial console code working properly and merged into the main
39 * version of the tree. Thanks to Randy Dunlap for the initial version
40 * of this code, and for pushing me to finish it up.
41 * The USB serial console works with any usb serial driver device.
42 *
43 * (03/21/2002) gkh
44 * Moved all manipulation of port->open_count into the core. Now the
45 * individual driver's open and close functions are called only when the
46 * first open() and last close() is called. Making the drivers a bit
47 * smaller and simpler.
48 * Fixed a bug if a driver didn't have the owner field set.
49 *
50 * (02/26/2002) gkh
51 * Moved all locking into the main serial_* functions, instead of having
52 * the individual drivers have to grab the port semaphore. This should
53 * reduce races.
54 * Reworked the MOD_INC logic a bit to always increment and decrement, even
55 * if the generic driver is being used.
56 *
57 * (10/10/2001) gkh
58 * usb_serial_disconnect() now sets the serial->dev pointer is to NULL to
59 * help prevent child drivers from accessing the device since it is now
60 * gone.
61 *
62 * (09/13/2001) gkh
63 * Moved generic driver initialize after we have registered with the USB
64 * core. Thanks to Randy Dunlap for pointing this problem out.
65 *
66 * (07/03/2001) gkh
67 * Fixed module paramater size. Thanks to John Brockmeyer for the pointer.
68 * Fixed vendor and product getting defined through the MODULE_PARM macro
69 * if the Generic driver wasn't compiled in.
70 * Fixed problem with generic_shutdown() not being called for drivers that
71 * don't have a shutdown() function.
72 *
73 * (06/06/2001) gkh
74 * added evil hack that is needed for the prolific pl2303 device due to the
75 * crazy way its endpoints are set up.
76 *
77 * (05/30/2001) gkh
78 * switched from using spinlock to a semaphore, which fixes lots of problems.
79 *
80 * (04/08/2001) gb
81 * Identify version on module load.
82 *
83 * 2001_02_05 gkh
84 * Fixed buffer overflows bug with the generic serial driver. Thanks to
85 * Todd Squires <squirest@ct0.com> for fixing this.
86 *
87 * (01/10/2001) gkh
88 * Fixed bug where the generic serial adaptor grabbed _any_ device that was
89 * offered to it.
90 *
91 * (12/12/2000) gkh
92 * Removed MOD_INC and MOD_DEC from poll and disconnect functions, and
93 * moved them to the serial_open and serial_close functions.
94 * Also fixed bug with there not being a MOD_DEC for the generic driver
95 * (thanks to Gary Brubaker for finding this.)
96 *
97 * (11/29/2000) gkh
98 * Small NULL pointer initialization cleanup which saves a bit of disk image
99 *
100 * (11/01/2000) Adam J. Richter
101 * instead of using idVendor/idProduct pairs, usb serial drivers
102 * now identify their hardware interest with usb_device_id tables,
103 * which they usually have anyhow for use with MODULE_DEVICE_TABLE.
104 *
105 * (10/05/2000) gkh
106 * Fixed bug with urb->dev not being set properly, now that the usb
107 * core needs it.
108 *
109 * (09/11/2000) gkh
110 * Removed DEBUG #ifdefs with call to usb_serial_debug_data
111 *
112 * (08/28/2000) gkh
113 * Added port_lock to port structure.
114 * Added locks for SMP safeness to generic driver
115 * Fixed the ability to open a generic device's port more than once.
116 *
117 * (07/23/2000) gkh
118 * Added bulk_out_endpointAddress to port structure.
119 *
120 * (07/19/2000) gkh, pberger, and borchers
121 * Modifications to allow usb-serial drivers to be modules.
122 *
123 * (07/03/2000) gkh
124 * Added more debugging to serial_ioctl call
125 *
126 * (06/25/2000) gkh
127 * Changed generic_write_bulk_callback to not call wake_up_interruptible
128 * directly, but to have port_softint do it at a safer time.
129 *
130 * (06/23/2000) gkh
131 * Cleaned up debugging statements in a quest to find UHCI timeout bug.
132 *
133 * (05/22/2000) gkh
134 * Changed the makefile, enabling the big CONFIG_USB_SERIAL_SOMTHING to be
135 * removed from the individual device source files.
136 *
137 * (05/03/2000) gkh
138 * Added the Digi Acceleport driver from Al Borchers and Peter Berger.
139 *
140 * (05/02/2000) gkh
141 * Changed devfs and tty register code to work properly now. This was based on
142 * the ACM driver changes by Vojtech Pavlik.
143 *
144 * (04/27/2000) Ryan VanderBijl
145 * Put calls to *_paranoia_checks into one function.
146 *
147 * (04/23/2000) gkh
148 * Fixed bug that Randy Dunlap found for Generic devices with no bulk out ports.
149 * Moved when the startup code printed out the devices that are supported.
150 *
151 * (04/19/2000) gkh
152 * Added driver for ZyXEL omni.net lcd plus ISDN TA
153 * Made startup info message specify which drivers were compiled in.
154 *
155 * (04/03/2000) gkh
156 * Changed the probe process to remove the module unload races.
157 * Changed where the tty layer gets initialized to have devfs work nicer.
158 * Added initial devfs support.
159 *
160 * (03/26/2000) gkh
161 * Split driver up into device specific pieces.
162 *
163 * (03/19/2000) gkh
164 * Fixed oops that could happen when device was removed while a program
165 * was talking to the device.
166 * Removed the static urbs and now all urbs are created and destroyed
167 * dynamically.
168 * Reworked the internal interface. Now everything is based on the
169 * usb_serial_port structure instead of the larger usb_serial structure.
170 * This fixes the bug that a multiport device could not have more than
171 * one port open at one time.
172 *
173 * (03/17/2000) gkh
174 * Added config option for debugging messages.
175 * Added patch for keyspan pda from Brian Warner.
176 *
177 * (03/06/2000) gkh
178 * Added the keyspan pda code from Brian Warner <warner@lothar.com>
179 * Moved a bunch of the port specific stuff into its own structure. This
180 * is in anticipation of the true multiport devices (there's a bug if you
181 * try to access more than one port of any multiport device right now)
182 *
183 * (02/21/2000) gkh
184 * Made it so that any serial devices only have to specify which functions
185 * they want to overload from the generic function calls (great,
186 * inheritance in C, in a driver, just what I wanted...)
187 * Added support for set_termios and ioctl function calls. No drivers take
188 * advantage of this yet.
189 * Removed the #ifdef MODULE, now there is no module specific code.
190 * Cleaned up a few comments in usb-serial.h that were wrong (thanks again
191 * to Miles Lott).
192 * Small fix to get_free_serial.
193 *
194 * (02/14/2000) gkh
195 * Removed the Belkin and Peracom functionality from the driver due to
196 * the lack of support from the vendor, and me not wanting people to
197 * accidenatly buy the device, expecting it to work with Linux.
198 * Added read_bulk_callback and write_bulk_callback to the type structure
199 * for the needs of the FTDI and WhiteHEAT driver.
200 * Changed all reverences to FTDI to FTDI_SIO at the request of Bill
201 * Ryder.
202 * Changed the output urb size back to the max endpoint size to make
203 * the ftdi_sio driver have it easier, and due to the fact that it didn't
204 * really increase the speed any.
205 *
206 * (02/11/2000) gkh
207 * Added VISOR_FUNCTION_CONSOLE to the visor startup function. This was a
208 * patch from Miles Lott (milos@insync.net).
209 * Fixed bug with not restoring the minor range that a device grabs, if
210 * the startup function fails (thanks Miles for finding this).
211 *
212 * (02/05/2000) gkh
213 * Added initial framework for the Keyspan PDA serial converter so that
214 * Brian Warner has a place to put his code.
215 * Made the ezusb specific functions generic enough that different
216 * devices can use them (whiteheat and keyspan_pda both need them).
217 * Split out a whole bunch of structure and other stuff to a separate
218 * usb-serial.h file.
219 * Made the Visor connection messages a little more understandable, now
220 * that Miles Lott (milos@insync.net) has gotten the Generic channel to
221 * work. Also made them always show up in the log file.
222 *
223 * (01/25/2000) gkh
224 * Added initial framework for FTDI serial converter so that Bill Ryder
225 * has a place to put his code.
226 * Added the vendor specific info from Handspring. Now we can print out
227 * informational debug messages as well as understand what is happening.
228 *
229 * (01/23/2000) gkh
230 * Fixed problem of crash when trying to open a port that didn't have a
231 * device assigned to it. Made the minor node finding a little smarter,
232 * now it looks to find a continuous space for the new device.
233 *
234 * (01/21/2000) gkh
235 * Fixed bug in visor_startup with patch from Miles Lott (milos@insync.net)
236 * Fixed get_serial_by_minor which was all messed up for multi port
237 * devices. Fixed multi port problem for generic devices. Now the number
238 * of ports is determined by the number of bulk out endpoints for the
239 * generic device.
240 *
241 * (01/19/2000) gkh
242 * Removed lots of cruft that was around from the old (pre urb) driver
243 * interface.
244 * Made the serial_table dynamic. This should save lots of memory when
245 * the number of minor nodes goes up to 256.
246 * Added initial support for devices that have more than one port.
247 * Added more debugging comments for the Visor, and added a needed
248 * set_configuration call.
249 *
250 * (01/17/2000) gkh
251 * Fixed the WhiteHEAT firmware (my processing tool had a bug)
252 * and added new debug loader firmware for it.
253 * Removed the put_char function as it isn't really needed.
254 * Added visor startup commands as found by the Win98 dump.
255 *
256 * (01/13/2000) gkh
257 * Fixed the vendor id for the generic driver to the one I meant it to be.
258 *
259 * (01/12/2000) gkh
260 * Forget the version numbering...that's pretty useless...
261 * Made the driver able to be compiled so that the user can select which
262 * converter they want to use. This allows people who only want the Visor
263 * support to not pay the memory size price of the WhiteHEAT.
264 * Fixed bug where the generic driver (idVendor=0000 and idProduct=0000)
265 * grabbed the root hub. Not good.
266 *
267 * version 0.4.0 (01/10/2000) gkh
268 * Added whiteheat.h containing the firmware for the ConnectTech WhiteHEAT
269 * device. Added startup function to allow firmware to be downloaded to
270 * a device if it needs to be.
271 * Added firmware download logic to the WhiteHEAT device.
272 * Started to add #defines to split up the different drivers for potential
273 * configuration option.
274 *
275 * version 0.3.1 (12/30/99) gkh
276 * Fixed problems with urb for bulk out.
277 * Added initial support for multiple sets of endpoints. This enables
278 * the Handspring Visor to be attached successfully. Only the first
279 * bulk in / bulk out endpoint pair is being used right now.
280 *
281 * version 0.3.0 (12/27/99) gkh
282 * Added initial support for the Handspring Visor based on a patch from
283 * Miles Lott (milos@sneety.insync.net)
284 * Cleaned up the code a bunch and converted over to using urbs only.
285 *
286 * version 0.2.3 (12/21/99) gkh
287 * Added initial support for the Connect Tech WhiteHEAT converter.
288 * Incremented the number of ports in expectation of getting the
289 * WhiteHEAT to work properly (4 ports per connection).
290 * Added notification on insertion and removal of what port the
291 * device is/was connected to (and what kind of device it was).
292 *
293 * version 0.2.2 (12/16/99) gkh
294 * Changed major number to the new allocated number. We're legal now!
295 *
296 * version 0.2.1 (12/14/99) gkh
297 * Fixed bug that happens when device node is opened when there isn't a
298 * device attached to it. Thanks to marek@webdesign.no for noticing this.
299 *
300 * version 0.2.0 (11/10/99) gkh
301 * Split up internals to make it easier to add different types of serial
302 * converters to the code.
303 * Added a "generic" driver that gets it's vendor and product id
304 * from when the module is loaded. Thanks to David E. Nelson (dnelson@jump.net)
305 * for the idea and sample code (from the usb scanner driver.)
306 * Cleared up any licensing questions by releasing it under the GNU GPL.
307 *
308 * version 0.1.2 (10/25/99) gkh
309 * Fixed bug in detecting device.
310 *
311 * version 0.1.1 (10/05/99) gkh
312 * Changed the major number to not conflict with anything else.
313 *
314 * version 0.1 (09/28/99) gkh
315 * Can recognize the two different devices and start up a read from
316 * device when asked to. Writes also work. No control signals yet, this
317 * all is vendor specific data (i.e. no spec), also no control for
318 * different baud rates or other bit settings.
319 * Currently we are using the same devid as the acm driver. This needs
320 * to change.

14 * 13 *
15 * (06/03/2003) Judd Montgomery <judd at jpilot.org>
16 * Added support for module parameter options for untested/unknown
17 * devices.
18 *
19 * (03/09/2003) gkh
20 * Added support for the Sony Clie NZ90V device. Thanks to Martin Brachtl
21 * <brachtl@redgrep.cz> for the information.
22 *
23 * (03/05/2003) gkh
24 * Think Treo support is now working.
25 *
26 * (04/03/2002) gkh
27 * Added support for the Sony OS 4.1 devices. Thanks to Hiroyuki ARAKI
28 * <hiro@zob.ne.jp> for the information.
29 *
30 * (03/27/2002) gkh
31 * Removed assumptions that port->tty was always valid (is not true
32 * for usb serial console devices.)
33 *
34 * (03/23/2002) gkh
35 * Added support for the Palm i705 device, thanks to Thomas Riemer
36 * <tom@netmech.com> for the information.
37 *
38 * (03/21/2002) gkh
39 * Added support for the Palm m130 device, thanks to Udo Eisenbarth
40 * <udo.eisenbarth@web.de> for the information.
41 *
42 * (02/27/2002) gkh
43 * Reworked the urb handling logic. We have no more pool, but dynamically
44 * allocate the urb and the transfer buffer on the fly. In testing this
45 * does not incure any measurable overhead. This also relies on the fact
46 * that we have proper reference counting logic for urbs.
47 *
48 * (02/21/2002) SilaS
49 * Added initial support for the Palm m515 devices.
50 *
51 * (02/14/2002) gkh
52 * Added support for the Clie S-360 device.
53 *
54 * (12/18/2001) gkh
55 * Added better Clie support for 3.5 devices. Thanks to Geoffrey Levand
56 * for the patch.
57 *
58 * (11/11/2001) gkh
59 * Added support for the m125 devices, and added check to prevent oopses
60 * for Clié devices that lie about the number of ports they have.
61 *
62 * (08/30/2001) gkh
63 * Added support for the Clie devices, both the 3.5 and 4.0 os versions.
64 * Many thanks to Daniel Burke, and Bryan Payne for helping with this.
65 *
66 * (08/23/2001) gkh
67 * fixed a few potential bugs pointed out by Oliver Neukum.
68 *
69 * (05/30/2001) gkh
70 * switched from using spinlock to a semaphore, which fixes lots of problems.
71 *
72 * (05/28/2000) gkh
73 * Added initial support for the Palm m500 and Palm m505 devices.
74 *
75 * (04/08/2001) gb
76 * Identify version on module load.
77 *
78 * (01/21/2000) gkh
79 * Added write_room and chars_in_buffer, as they were previously using the
80 * generic driver versions which is all wrong now that we are using an urb
81 * pool. Thanks to Wolfgang Grandegger for pointing this out to me.
82 * Removed count assignment in the write function, which was not needed anymore
83 * either. Thanks to Al Borchers for pointing this out.
84 *
85 * (12/12/2000) gkh
86 * Moved MOD_DEC to end of visor_close to be nicer, as the final write
87 * message can sleep.
88 *
89 * (11/12/2000) gkh
90 * Fixed bug with data being dropped on the floor by forcing tty->low_latency
91 * to be on. Hopefully this fixes the OHCI issue!
92 *
93 * (11/01/2000) Adam J. Richter
94 * usb_device_id table support
95 *
96 * (10/05/2000) gkh
97 * Fixed bug with urb->dev not being set properly, now that the usb
98 * core needs it.
99 *
100 * (09/11/2000) gkh
101 * Got rid of always calling kmalloc for every urb we wrote out to the
102 * device.
103 * Added visor_read_callback so we can keep track of bytes in and out for
104 * those people who like to know the speed of their device.
105 * Removed DEBUG #ifdefs with call to usb_serial_debug_data
106 *
107 * (09/06/2000) gkh
108 * Fixed oops in visor_exit. Need to uncomment usb_unlink_urb call _after_
109 * the host controller drivers set urb->dev = NULL when the urb is finished.
110 *
111 * (08/28/2000) gkh
112 * Added locks for SMP safeness.
113 *
114 * (08/08/2000) gkh
115 * Fixed endian problem in visor_startup.
116 * Fixed MOD_INC and MOD_DEC logic and the ability to open a port more
117 * than once.
118 *
119 * (07/23/2000) gkh
120 * Added pool of write urbs to speed up transfers to the visor.
121 *
122 * (07/19/2000) gkh
123 * Added module_init and module_exit functions to handle the fact that this
124 * driver is a loadable module now.
125 *
126 * (07/03/2000) gkh
127 * Added visor_set_ioctl and visor_set_termios functions (they don't do much
128 * of anything, but are good for debugging.)
129 *
130 * (06/25/2000) gkh
131 * Fixed bug in visor_unthrottle that should help with the disconnect in PPP
132 * bug that people have been reporting.
133 *
134 * (06/23/2000) gkh
135 * Cleaned up debugging statements in a quest to find UHCI timeout bug.
136 *
137 * (04/27/2000) Ryan VanderBijl
138 * Fixed memory leak in visor_close
139 *
140 * (03/26/2000) gkh
141 * Split driver up into device specific pieces.
