* Convert files to UTF-8.
  * Also correct some people's names
    (one example is Eißfeldt, which was found in a source file.
    Given that the author used an ß at all in a source file
    indicates that the real name has in fact a 'ß' and not an 'ss',
    which is commonly used as a substitute for 'ß' when limited to
    7bit.)
  * Correct town names (Goettingen -> Göttingen)
  * Update Eberhard Mönkeberg's address (http://lkml.org/lkml/2007/1/8/313)

| 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  They were quite old, and out of date, and we don't keep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.
 | |
| 
 | |
|  (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.
 | |
| 
 | |
| -----------------------------------------------------------------------
 | |
| 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.
 | |
| 
 | |
|  (03/09/2003) gkh
 | |
| 	Added support for the Sony Clie NZ90V device.  Thanks to Martin Brachtl
 | |
| 	<brachtl@redgrep.cz> for the information.

 | |
| 	<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.

 | |
| 	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

| 	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

 | |
| 	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

 | |
| 	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
 | |
| 
 | |

 | |
| 	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.
