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 They were quite old, and out of date, and we don't keep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

Added support for module parameter options for untested/unknown
|
||||
devices.
|
||||
|
||||
(03/09/2003) 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.
|

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.

||||
Added visor_set_ioctl and visor_set_termios functions (they don't do much

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.

*
|

* 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
|

* gone.
|

*
|

* (04/19/2000) gkh

* (04/03/2000) gkh
|

* (03/26/2000) gkh
|

* (03/19/2000) gkh
|

|
||||
* 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.

|
||||
* devices.
|
||||
*
|
||||
* (03/09/2003) gkh
|

|

* for usb serial console devices.)
|

*
|
||||
* (03/23/2002) gkh

* <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
|
||||
* 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
|
||||
*
|
||||
