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 They were quite old, and out of date, and we don't keep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.

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

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

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

<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 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

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, firmware 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.

* -- Added support for break signals.
*
* (7/25/2000) pberger
* -- Added USB-2 support. Note: the USB-2 supports 3 devices: two
* serial and a parallel port. The parallel port is implemented
* as a serial-to-parallel converter. That is, the driver actually
* presents all three USB-2 interfaces as serial ports, but the third
* one physically connects to a parallel device. Thus, for example,
* one could plug a parallel printer into the USB-2's third port,
* but from the kernel's (and userland's) point of view what's
* actually out there is a serial device.

* -- Keep count of opens and dec the module use count for each
* outstanding open when shutdown is called (on disconnect).
* -- Fixed sanity checks in read_bulk_callback and write_bulk_callback
* so pointers are checked before use.
* -- Split read bulk callback into in band and out of band
* callbacks, and no longer restart read chains if there is
* a status error or a sanity error. This fixed the seg
* faults and other errors we used to get on disconnect.
* -- Port->active is once again a flag as usb-serial intended it
* to be, not a count. Since it was only a char it would
* have been limited to 256 simultaneous opens. Now the open

* (6/27/2000) pberger and borchers
* -- Zeroed out sync field in the wakeup_task before first use;

* -- In digi_set_modem_signals the inner nested spin locks use just
* spin_lock() rather than spin_lock_irqsave(). The old code

* -- copy_from_user (which can sleep) is no longer called while a
* spinlock is held. We copy to a local buffer before getting
* the spinlock--don't like the extra copy but the code is simpler.
* -- Printk and dbg are no longer called while a spin lock is held.
*
* (6/4/2000) pberger and borchers
* -- Replaced separate calls to spin_unlock_irqrestore and
* interruptible_sleep_on_timeout with a new function
* cond_wait_interruptible_timeout_irqrestore. This eliminates
* the race condition where the wake up could happen after
* the unlock and before the sleep.
* -- Close now waits for output to drain.
* -- Open waits until any close in progress is finished.
* -- All out of band responses are now processed, not just the
* first in a USB packet.
* -- Fixed a bug that prevented the driver from working when the
* first Digi port was not the first USB serial port--the driver
* was mistakenly using the external USB serial port number to
* try to index into its internal ports.
* -- Fixed an SMP bug -- write_bulk_callback is called directly from
* an interrupt, so spin_lock_irqsave/spin_unlock_irqrestore are
* needed for locks outside write_bulk_callback that are also
* acquired by write_bulk_callback to prevent deadlocks.
* -- Fixed support for select() by making digi_chars_in_buffer()
* return 256 when -EINPROGRESS is set, as the line discipline
* code in n_tty.c expects.
* -- Fixed an include file ordering problem that prevented debugging
* messages from working.
* -- Fixed an intermittent timeout problem that caused writes to
* sometimes get stuck on some machines on some kernels. It turns
* out in these circumstances write_chan() (in n_tty.c) was
* asleep waiting for our wakeup call. Even though we call
* wake_up_interruptible() in digi_write_bulk_callback(), there is
* a race condition that could cause the wakeup to fail: if our
* wake_up_interruptible() call occurs between the time that our
* driver write routine finishes and write_chan() sets current->state
* to TASK_INTERRUPTIBLE, the effect of our wakeup setting the state
* to TASK_RUNNING will be lost and write_chan's subsequent call to
* schedule() will never return (unless it catches a signal).
* This race condition occurs because write_bulk_callback() (and thus
* the wakeup) are called asynchronously from an interrupt, rather than
* from the scheduler. We can avoid the race by calling the wakeup
* from the scheduler queue and that's our fix: Now, at the end of
* write_bulk_callback() we queue up a wakeup call on the scheduler
* task queue. We still also invoke the wakeup directly since that
* squeezes a bit more performance out of the driver, and any lost
* race conditions will get cleaned up at the next scheduler run.
*
* NOTE: The problem also goes away if you comment out
* the two code lines in write_chan() where current->state
* is set to TASK_RUNNING just before calling driver.write() and to
* TASK_INTERRUPTIBLE immediately afterwards. This is why the
* problem did not show up with the 2.2 kernels -- they do not
* include that code.
*
* (5/16/2000) pberger and borchers
* -- Added timeouts to sleeps, to defend against lost wake ups.
* -- Handle transition to/from B0 baud rate in digi_set_termios.
*
* (5/13/2000) pberger and borchers
* -- All commands now sent on out of band port, using
* digi_write_oob_command.
* -- Get modem control signals whenever they change, support TIOCMGET/
* SET/BIS/BIC ioctls.
* -- digi_set_termios now supports parity, word size, stop bits, and
* receive enable.
* -- Cleaned up open and close, use digi_set_termios and
* digi_write_oob_command to set port parameters.
* -- Added digi_startup_device to start read chains on all ports.
* -- Write buffer is only used when count==1, to be sure put_char can
* write a char (unless the buffer is full).
*
* (5/10/2000) pberger and borchers
* -- Added MOD_INC_USE_COUNT/MOD_DEC_USE_COUNT calls on open/close.
* -- Fixed problem where the first incoming character is lost on
* port opens after the first close on that port. Now we keep
* the read_urb chain open until shutdown.
* -- Added more port conditioning calls in digi_open and digi_close.
* -- Convert port->active to a use count so that we can deal with multiple
* opens and closes properly.
* -- Fixed some problems with the locking code.
*
* (5/3/2000) pberger and borchers
* -- First alpha version of the driver--many known limitations and bugs.
*
*
* Locking and SMP
*
* - Each port, including the out-of-band port, has a lock used to
* serialize all access to the port's private structure.
* - The port lock is also used to serialize all writes and access to
* the port's URB.
* - The port lock is also used for the port write_wait condition
* variable. Holding the port lock will prevent a wake up on the
* port's write_wait; this can be used with cond_wait_... to be sure
* the wake up is not lost in a race when dropping the lock and
* sleeping waiting for the wakeup.
* - digi_write() does not sleep, since it is sometimes called on
* interrupt time.
* - digi_write_bulk_callback() and digi_read_bulk_callback() are
* called directly from interrupts. Hence spin_lock_irqsave()
* and spin_unlock_irqrestore() are used in the rest of the code
* for any locks they acquire.
* - digi_write_bulk_callback() gets the port lock before waking up
* processes sleeping on the port write_wait. It also schedules
* wake ups so they happen from the scheduler, because the tty
* system can miss wake ups from interrupts.
* - All sleeps use a timeout of DIGI_RETRY_TIMEOUT before looping to
* recheck the condition they are sleeping on. This is defensive,
* in case a wake up is lost.
* - Following Documentation/DocBook/kernel-locking.tmpl no spin locks
* are held when calling copy_to/from_user or printk.

* transmitted to RS-232 devices which don't assert the 'CTS' signal.
*
* 10-Nov-2001 Wolfgang Grandegger
* - Fixed an endianess problem with the baudrate selection for PowerPC.
*
* 06-Dec-2001 Martin Hamilton <martinh@gnu.org>
* - Added support for the Belkin F5U109 DB9 adaptor
*
* 30-May-2001 Greg Kroah-Hartman
* - switched from using spinlock to a semaphore, which fixes lots of
* problems.
*
* 04-May-2001 Stelian Pop
* - Set the maximum bulk output size for Sitecom U232-P25 model to 16 bytes
* instead of the device reported 32 (using 32 bytes causes many data
* loss, Windows driver uses 16 too).
*
* 02-May-2001 Stelian Pop
* - Fixed the baud calculation for Sitecom U232-P25 model
*
* 08-Apr-2001 gb
* - Identify version on module load.
*
* 06-Jan-2001 Cornel Ciocirlan
* - Added support for Sitecom U232-P25 model (Product Id 0x0230)
* - Added support for D-Link DU-H3SP USB BAY (Product Id 0x0200)
*
* 29-Nov-2000 Greg Kroah-Hartman
* - Added device id table to fit with 2.4.0-test11 structure.
* - took out DEAL_WITH_TWO_INT_IN_ENDPOINTS #define as it's not needed
* (lots of things will change if/when the usb-serial core changes to
* handle these issues.
*
* 27-Nov-2000 Wolfgang Grandegge
* A version for kernel 2.4.0-test10 released to the Linux community
* (via linux-usb-devel).
