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.

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. - * */ #include <linux/config.h> diff --git a/drivers/usb/serial/usb-serial.h b/drivers/usb/serial/usb-serial.h index 4ca5e0c0561..1cedc199950 100644 --- a/drivers/usb/serial/usb-serial.h +++ b/drivers/usb/serial/usb-serial.h @@ -1,53 +1,13 @@ /* * USB Serial Converter driver * - * Copyright (C) 1999 - 2004 + * Copyright (C) 1999 - 2005 * Greg Kroah-Hartman (greg@kroah.com) * * This program is free software; you can redistribute it and/or modify * it under the terms of the GNU General Public License as published by - * the Free Software Foundation; either version 2 of the License, or - * (at your option) any later version. + * the Free Software Foundation; either version 2 of the License. * - * See Documentation/usb/usb-serial.txt for more information on using this driver - * - * (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.
