linux-vybrid_public/drivers/usb/serial/ChangeLog.history

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  They were quite old, and out of date, and we don't keep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

-----------------------------------------------------------------------
usb-serial.h Change Log comments:

 (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.  Needed to determine device
	owner when the device is disconnected.

 (05/30/2001) gkh
	added sem to port structure and removed port_lock

 (10/05/2000) gkh
	Added interrupt_in_endpointAddress and bulk_in_endpointAddress to help
	fix bug with urb->dev not being set properly, now that the usb core
	needs it.

 (09/11/2000) gkh
	Added usb_serial_debug_data function to help get rid of #DEBUG in the
	drivers.

 (08/28/2000) gkh
	Added port_lock to port structure.

 (08/08/2000) gkh
	Added open_count to port structure.

	Modifications to allow usb-serial drivers to be modules.

-----------------------------------------------------------------------
usb-serial.c Change Log comments:

 (12/10/2002) gkh
	Split the ports off into their own struct device, and added a
	usb-serial bus driver.

 (11/19/2002) gkh
	removed a few #ifdefs for the generic code and cleaned up the failure
	logic in initialization.

 (10/02/2002) gkh
	moved the console code to console.c and out of this file.

 (06/05/2002) gkh
	moved location of startup() call in serial_probe() until after all
	of the port information and endpoints are initialized.  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.

 (03/05/2003) 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.

	<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.

	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.  Thanks to joe@bndlg.de for parts of it.

 2001_Sep_19 gkh
	Added break support.

 2001_Aug_30 gkh
	fixed oops in write_bulk_callback.

 2001_Aug_28 gkh
	reworked buffer logic to be like other usb-serial drivers.  Hopefully
	removing some reported problems.

 2001_Jun_06 gkh
	finished porting to 2.4 format.


-----------------------------------------------------------------------

	Release to IO networks.
	Fixed problems that were seen in code by David.
  Now both Edgeport/4 and Edgeport/2 works properly.
  Changed most of the functions to use port instead of serial.

 0.7 (02/27/2000) greg kroah-hartman
	Milestone 3 release.
	Release to IO Networks
	ioctl for waiting on line change implemented.
	ioctl for getting statistics implemented.
	multiport support working.
	lsr and msr registers are now handled properly.
	change break now hooked up and working.
	support for all known Edgeport devices.

 0.6 (02/22/2000) greg kroah-hartman
	Release to IO networks.
	CHASE is implemented correctly when port is closed.
	SerialOpen now blocks correctly until port is fully opened.

 0.5 (02/20/2000) greg kroah-hartman
	Release to IO networks.
	Known problems:
		modem status register changes are not sent on to the user
		CHASE is not implemented when the port is closed.

 0.4 (02/16/2000) greg kroah-hartman
	Second cut at the CeBit demo.
	Doesn't leak memory on every write to the port
	Still small leaks on startup.
	Added support for Edgeport/2 and Edgeport/8

 0.3 (02/15/2000) greg kroah-hartman
	CeBit demo release.
	Force the line settings to 4800, 8, 1, e for the demo.
	Warning! This version leaks memory like crazy!

 0.2 (01/30/2000) greg kroah-hartman
	Milestone 1 release.
	Device is found by USB subsystem, enumerated, fimware is downloaded
	and the descriptors are printed to the debug log, config is set, and
	green light starts to blink. Open port works, and data can be sent
	and received at the default settings of the UART. Loopback connector
	and debug log confirms this.

 0.1 (01/23/2000) greg kroah-hartman
	Initial release to help IO Networks try to set up their test system.
	Edgeport4 is recognized, firmware is downloaded, config is set so
	device blinks green light every 3 sec. Port is bound, but opening,
	closing, and sending data do not work properly.
