[linux-2.6] / 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  They were quite old, and out of date, and we don't keep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.

 (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.

 (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
        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.


-----------------------------------------------------------------------
io_edgeport.c Change Log comments:

 2003_04_03 al borchers
  - fixed a bug (that shows up with dosemu) where the tty struct is
    used in a callback after it has been freed

 2.3 2002_03_08 greg kroah-hartman
        - fixed bug when multiple devices were attached at the same time.

 2.2 2001_11_14 greg kroah-hartman
        - fixed bug in edge_close that kept the port from being used more
          than once.
        - fixed memory leak on device removal.
        - fixed potential double free of memory when command urb submitting
          failed.
        - other small cleanups when the device is removed

 2.1 2001_07_09 greg kroah-hartman
        - added support for TIOCMBIS and TIOCMBIC.

     (04/08/2001) gb
        - Identify version on module load.

 2.0 2001_03_05 greg kroah-hartman

 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.
