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 - * Fixed unsafe spinlock usage in ftdi_write - * - * (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. * */ |
