*
* See Documentation/usb/usb-serial.txt for more information on using this driver
*
* 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
* 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.
*
* (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
+ * 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.
*
* (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
+ * 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.
*
* (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.
* (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.
*
* 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.
* 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
*
* Added module_init and module_exit functions to handle the fact that this
* driver is a loadable module now.
*
- * (04/04/2000) Bill Ryder
+ * (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
+ * (03/30/2000) Bill Ryder
* Implemented lots of ioctls
* Fixed a race condition in write
* Changed some dbg's to errs
/* to talk to the device */
/* Thanx to gkh and the rest of the usb dev group for all code I have assimilated :-) */
