*
* See Documentation/usb/usb-serial.txt for more information on using this driver
*
- * (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 CliƩ 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.
- *
