Prefs
   1This is the contents of some of the drivers/usb/serial/ files that had  old
   2changelog comments.  They were quite old, and out of date, and we don't keep
   3them anymore, so I've put them here, away from the source files, in case
   4people still care to see them.

   9usb-serial.h Change Log comments:
  10
  11 (03/26/2002) gkh
  12        removed the port->tty check from port_paranoia_check() due to serial
  13        consoles not having a tty device assigned to them.
  14
  15 (12/03/2001) gkh
  16        removed active from the port structure.
  17        added documentation to the usb_serial_device_type structure
  18
  19 (10/10/2001) gkh
  20        added vendor and product to serial structure.  Needed to determine device
  21        owner when the device is disconnected.
  22
  23 (05/30/2001) gkh
  24        added sem to port structure and removed port_lock
  25
  26 (10/05/2000) gkh
  27        Added interrupt_in_endpointAddress and bulk_in_endpointAddress to help
  28        fix bug with urb->dev not being set properly, now that the usb core
  29        needs it.
  30
  31 (09/11/2000) gkh
  32        Added usb_serial_debug_data function to help get rid of #DEBUG in the
  33        drivers.
  34
  35 (08/28/2000) gkh
  36        Added port_lock to port structure.
  37
  38 (08/08/2000) gkh
  39        Added open_count to port structure.
  40
  41 (07/23/2000) gkh
  42        Added bulk_out_endpointAddress to port structure.
  43
  44 (07/19/2000) gkh, pberger, and borchers
  45        Modifications to allow usb-serial drivers to be modules.

  48usb-serial.c Change Log comments:
  49
  50 (12/10/2002) gkh
  51        Split the ports off into their own struct device, and added a
  52        usb-serial bus driver.
  53
  54 (11/19/2002) gkh
  55        removed a few #ifdefs for the generic code and cleaned up the failure
  56        logic in initialization.
  57
  58 (10/02/2002) gkh
  59        moved the console code to console.c and out of this file.
  60
  61 (06/05/2002) gkh
  62        moved location of startup() call in serial_probe() until after all
  63        of the port information and endpoints are initialized.  This makes
  64        things easier for some drivers.
  65
  66 (04/10/2002) gkh
  67        added serial_read_proc function which creates a
  68        /proc/tty/driver/usb-serial file.
  69
  70 (03/27/2002) gkh
  71        Got USB serial console code working properly and merged into the main
  72        version of the tree.  Thanks to Randy Dunlap for the initial version
  73        of this code, and for pushing me to finish it up.
  74        The USB serial console works with any usb serial driver device.
  75
  76 (03/21/2002) gkh
  77        Moved all manipulation of port->open_count into the core.  Now the
  78        individual driver's open and close functions are called only when the
  79        first open() and last close() is called.  Making the drivers a bit
  80        smaller and simpler.
  81        Fixed a bug if a driver didn't have the owner field set.
  82
  83 (02/26/2002) gkh
  84        Moved all locking into the main serial_* functions, instead of having
  85        the individual drivers have to grab the port semaphore.  This should
  86        reduce races.
  87        Reworked the MOD_INC logic a bit to always increment and decrement, even
  88        if the generic driver is being used.
  89
  90 (10/10/2001) gkh
  91        usb_serial_disconnect() now sets the serial->dev pointer is to NULL to
  92        help prevent child drivers from accessing the device since it is now
  93        gone.
  94
  95 (09/13/2001) gkh
  96        Moved generic driver initialize after we have registered with the USB
  97        core.  Thanks to Randy Dunlap for pointing this problem out.
  98
  99 (07/03/2001) gkh
 100        Fixed module paramater size.  Thanks to John Brockmeyer for the pointer.
 101        Fixed vendor and product getting defined through the MODULE_PARM macro
 102        if the Generic driver wasn't compiled in.
 103        Fixed problem with generic_shutdown() not being called for drivers that
 104        don't have a shutdown() function.
 105
 106 (06/06/2001) gkh
 107        added evil hack that is needed for the prolific pl2303 device due to the
 108        crazy way its endpoints are set up.
 109
 110 (05/30/2001) gkh
 111        switched from using spinlock to a semaphore, which fixes lots of problems.
 112
 113 (04/08/2001) gb
 114        Identify version on module load.
 115
 116 2001_02_05 gkh
 117        Fixed buffer overflows bug with the generic serial driver.  Thanks to
 118        Todd Squires <squirest@ct0.com> for fixing this.
 119
 120 (01/10/2001) gkh
 121        Fixed bug where the generic serial adaptor grabbed _any_ device that was
 122        offered to it.
 123
 124 (12/12/2000) gkh
 125        Removed MOD_INC and MOD_DEC from poll and disconnect functions, and
 126        moved them to the serial_open and serial_close functions.
 127        Also fixed bug with there not being a MOD_DEC for the generic driver
 128        (thanks to Gary Brubaker for finding this.)
 129
 130 (11/29/2000) gkh
 131        Small NULL pointer initialization cleanup which saves a bit of disk image
 132
 133 (11/01/2000) Adam J. Richter
 134        instead of using idVendor/idProduct pairs, usb serial drivers
 135        now identify their hardware interest with usb_device_id tables,
 136        which they usually have anyhow for use with MODULE_DEVICE_TABLE.
 137
 138 (10/05/2000) gkh
 139        Fixed bug with urb->dev not being set properly, now that the usb
 140        core needs it.
 141
 142 (09/11/2000) gkh
 143        Removed DEBUG #ifdefs with call to usb_serial_debug_data
 144
 145 (08/28/2000) gkh
 146        Added port_lock to port structure.
 147        Added locks for SMP safeness to generic driver
 148        Fixed the ability to open a generic device's port more than once.
 149
 150 (07/23/2000) gkh
 151        Added bulk_out_endpointAddress to port structure.
 152
 153 (07/19/2000) gkh, pberger, and borchers
 154        Modifications to allow usb-serial drivers to be modules.
 155
 156 (07/03/2000) gkh
 157        Added more debugging to serial_ioctl call
 158
 159 (06/25/2000) gkh
 160        Changed generic_write_bulk_callback to not call wake_up_interruptible
 161        directly, but to have port_softint do it at a safer time.
 162
 163 (06/23/2000) gkh
 164        Cleaned up debugging statements in a quest to find UHCI timeout bug.
 165
 166 (05/22/2000) gkh
 167        Changed the makefile, enabling the big CONFIG_USB_SERIAL_SOMTHING to be
 168        removed from the individual device source files.
 169
 170 (05/03/2000) gkh
 171        Added the Digi Acceleport driver from Al Borchers and Peter Berger.
 172
 173 (05/02/2000) gkh
 174        Changed devfs and tty register code to work properly now. This was based on
 175        the ACM driver changes by Vojtech Pavlik.
 176
 177 (04/27/2000) Ryan VanderBijl
 178        Put calls to *_paranoia_checks into one function.
 179
 180 (04/23/2000) gkh
 181        Fixed bug that Randy Dunlap found for Generic devices with no bulk out ports.
 182        Moved when the startup code printed out the devices that are supported.
 183
 184 (04/19/2000) gkh
 185        Added driver for ZyXEL omni.net lcd plus ISDN TA
 186        Made startup info message specify which drivers were compiled in.
 187
 188 (04/03/2000) gkh
 189        Changed the probe process to remove the module unload races.
 190        Changed where the tty layer gets initialized to have devfs work nicer.
 191        Added initial devfs support.
 192
 193 (03/26/2000) gkh
 194        Split driver up into device specific pieces.
 195
 196 (03/19/2000) gkh
 197        Fixed oops that could happen when device was removed while a program
 198        was talking to the device.
 199        Removed the static urbs and now all urbs are created and destroyed
 200        dynamically.
 201        Reworked the internal interface. Now everything is based on the
 202        usb_serial_port structure instead of the larger usb_serial structure.
 203        This fixes the bug that a multiport device could not have more than
 204        one port open at one time.
 205
 206 (03/17/2000) gkh
 207        Added config option for debugging messages.
 208        Added patch for keyspan pda from Brian Warner.
 209
 210 (03/06/2000) gkh
 211        Added the keyspan pda code from Brian Warner <warner@lothar.com>
 212        Moved a bunch of the port specific stuff into its own structure. This
 213        is in anticipation of the true multiport devices (there's a bug if you
 214        try to access more than one port of any multiport device right now)
 215
 216 (02/21/2000) gkh
 217        Made it so that any serial devices only have to specify which functions
 218        they want to overload from the generic function calls (great,
 219        inheritance in C, in a driver, just what I wanted...)
 220        Added support for set_termios and ioctl function calls. No drivers take
 221        advantage of this yet.
 222        Removed the #ifdef MODULE, now there is no module specific code.
 223        Cleaned up a few comments in usb-serial.h that were wrong (thanks again
 224        to Miles Lott).
 225        Small fix to get_free_serial.
 226
 227 (02/14/2000) gkh
 228        Removed the Belkin and Peracom functionality from the driver due to
 229        the lack of support from the vendor, and me not wanting people to
 230        accidenatly buy the device, expecting it to work with Linux.
 231        Added read_bulk_callback and write_bulk_callback to the type structure
 232        for the needs of the FTDI and WhiteHEAT driver.
 233        Changed all reverences to FTDI to FTDI_SIO at the request of Bill
 234        Ryder.
 235        Changed the output urb size back to the max endpoint size to make
 236        the ftdi_sio driver have it easier, and due to the fact that it didn't
 237        really increase the speed any.
 238
 239 (02/11/2000) gkh
 240        Added VISOR_FUNCTION_CONSOLE to the visor startup function. This was a
 241        patch from Miles Lott (milos@insync.net).
 242        Fixed bug with not restoring the minor range that a device grabs, if
 243        the startup function fails (thanks Miles for finding this).
 244
 245 (02/05/2000) gkh
 246        Added initial framework for the Keyspan PDA serial converter so that
 247        Brian Warner has a place to put his code.
 248        Made the ezusb specific functions generic enough that different
 249        devices can use them (whiteheat and keyspan_pda both need them).
 250        Split out a whole bunch of structure and other stuff to a separate
 251        usb-serial.h file.
 252        Made the Visor connection messages a little more understandable, now
 253        that Miles Lott (milos@insync.net) has gotten the Generic channel to
 254        work. Also made them always show up in the log file.
 255
 256 (01/25/2000) gkh
 257        Added initial framework for FTDI serial converter so that Bill Ryder
 258        has a place to put his code.
 259        Added the vendor specific info from Handspring. Now we can print out
 260        informational debug messages as well as understand what is happening.
 261
 262 (01/23/2000) gkh
 263        Fixed problem of crash when trying to open a port that didn't have a
 264        device assigned to it. Made the minor node finding a little smarter,
 265        now it looks to find a continuous space for the new device.
 266
 267 (01/21/2000) gkh
 268        Fixed bug in visor_startup with patch from Miles Lott (milos@insync.net)
 269        Fixed get_serial_by_minor which was all messed up for multi port
 270        devices. Fixed multi port problem for generic devices. Now the number
 271        of ports is determined by the number of bulk out endpoints for the
 272        generic device.
 273
 274 (01/19/2000) gkh
 275        Removed lots of cruft that was around from the old (pre urb) driver
 276        interface.
 277        Made the serial_table dynamic. This should save lots of memory when
 278        the number of minor nodes goes up to 256.
 279        Added initial support for devices that have more than one port.
 280        Added more debugging comments for the Visor, and added a needed
 281        set_configuration call.
 282
 283 (01/17/2000) gkh
 284        Fixed the WhiteHEAT firmware (my processing tool had a bug)
 285        and added new debug loader firmware for it.
 286        Removed the put_char function as it isn't really needed.
 287        Added visor startup commands as found by the Win98 dump.
 288
 289 (01/13/2000) gkh
 290        Fixed the vendor id for the generic driver to the one I meant it to be.
 291
 292 (01/12/2000) gkh
 293        Forget the version numbering...that's pretty useless...
 294        Made the driver able to be compiled so that the user can select which
 295        converter they want to use. This allows people who only want the Visor
 296        support to not pay the memory size price of the WhiteHEAT.
 297        Fixed bug where the generic driver (idVendor=0000 and idProduct=0000)
 298        grabbed the root hub. Not good.
 299
 300 version 0.4.0 (01/10/2000) gkh
 301        Added whiteheat.h containing the firmware for the ConnectTech WhiteHEAT
 302        device. Added startup function to allow firmware to be downloaded to
 303        a device if it needs to be.
 304        Added firmware download logic to the WhiteHEAT device.
 305        Started to add #defines to split up the different drivers for potential
 306        configuration option.
 307
 308 version 0.3.1 (12/30/99) gkh
 309      Fixed problems with urb for bulk out.
 310      Added initial support for multiple sets of endpoints. This enables
 311      the Handspring Visor to be attached successfully. Only the first
 312      bulk in / bulk out endpoint pair is being used right now.
 313
 314 version 0.3.0 (12/27/99) gkh
 315        Added initial support for the Handspring Visor based on a patch from
 316        Miles Lott (milos@sneety.insync.net)
 317        Cleaned up the code a bunch and converted over to using urbs only.
 318
 319 version 0.2.3 (12/21/99) gkh
 320        Added initial support for the Connect Tech WhiteHEAT converter.
 321        Incremented the number of ports in expectation of getting the
 322        WhiteHEAT to work properly (4 ports per connection).
 323        Added notification on insertion and removal of what port the
 324        device is/was connected to (and what kind of device it was).
 325
 326 version 0.2.2 (12/16/99) gkh
 327        Changed major number to the new allocated number. We're legal now!
 328
 329 version 0.2.1 (12/14/99) gkh
 330        Fixed bug that happens when device node is opened when there isn't a
 331        device attached to it. Thanks to marek@webdesign.no for noticing this.
 332
 333 version 0.2.0 (11/10/99) gkh
 334        Split up internals to make it easier to add different types of serial
 335        converters to the code.
 336        Added a "generic" driver that gets it's vendor and product id
 337        from when the module is loaded. Thanks to David E. Nelson (dnelson@jump.net)
 338        for the idea and sample code (from the usb scanner driver.)
 339        Cleared up any licensing questions by releasing it under the GNU GPL.
 340
 341 version 0.1.2 (10/25/99) gkh
 342        Fixed bug in detecting device.
 343
 344 version 0.1.1 (10/05/99) gkh
 345        Changed the major number to not conflict with anything else.
 346
 347 version 0.1 (09/28/99) gkh
 348        Can recognize the two different devices and start up a read from
 349        device when asked to. Writes also work. No control signals yet, this
 350        all is vendor specific data (i.e. no spec), also no control for
 351        different baud rates or other bit settings.
 352        Currently we are using the same devid as the acm driver. This needs
 353        to change.

 356visor.c Change Log comments:
 357
 358 (06/03/2003) Judd Montgomery <judd at jpilot.org>
 359     Added support for module parameter options for untested/unknown
 360     devices.
 361
 362 (03/09/2003) gkh
 363        Added support for the Sony Clie NZ90V device.  Thanks to Martin Brachtl
 364        <brachtl@redgrep.cz> for the information.
 365
 366 (03/05/2003) gkh
 367        Think Treo support is now working.
 368
 369 (04/03/2002) gkh
 370        Added support for the Sony OS 4.1 devices.  Thanks to Hiroyuki ARAKI
 371        <hiro@zob.ne.jp> for the information.
 372
 373 (03/27/2002) gkh
 374        Removed assumptions that port->tty was always valid (is not true
 375        for usb serial console devices.)
 376
 377 (03/23/2002) gkh
 378        Added support for the Palm i705 device, thanks to Thomas Riemer
 379        <tom@netmech.com> for the information.
 380
 381 (03/21/2002) gkh
 382        Added support for the Palm m130 device, thanks to Udo Eisenbarth
 383        <udo.eisenbarth@web.de> for the information.
 384
 385 (02/27/2002) gkh
 386        Reworked the urb handling logic.  We have no more pool, but dynamically
 387        allocate the urb and the transfer buffer on the fly.  In testing this
 388        does not incure any measurable overhead.  This also relies on the fact
 389        that we have proper reference counting logic for urbs.
 390
 391 (02/21/2002) SilaS
 392  Added initial support for the Palm m515 devices.
 393
 394 (02/14/2002) gkh
 395        Added support for the Clie S-360 device.
 396
 397 (12/18/2001) gkh
 398        Added better Clie support for 3.5 devices.  Thanks to Geoffrey Levand
 399        for the patch.
 400
 401 (11/11/2001) gkh
 402        Added support for the m125 devices, and added check to prevent oopses
 403        for CliƩ devices that lie about the number of ports they have.
 404
 405 (08/30/2001) gkh
 406        Added support for the Clie devices, both the 3.5 and 4.0 os versions.
 407        Many thanks to Daniel Burke, and Bryan Payne for helping with this.
 408
 409 (08/23/2001) gkh
 410        fixed a few potential bugs pointed out by Oliver Neukum.
 411
 412 (05/30/2001) gkh
 413        switched from using spinlock to a semaphore, which fixes lots of problems.
 414
 415 (05/28/2000) gkh
 416        Added initial support for the Palm m500 and Palm m505 devices.
 417
 418 (04/08/2001) gb
 419        Identify version on module load.
 420
 421 (01/21/2000) gkh
 422        Added write_room and chars_in_buffer, as they were previously using the
 423        generic driver versions which is all wrong now that we are using an urb
 424        pool.  Thanks to Wolfgang Grandegger for pointing this out to me.
 425        Removed count assignment in the write function, which was not needed anymore
 426        either.  Thanks to Al Borchers for pointing this out.
 427
 428 (12/12/2000) gkh
 429        Moved MOD_DEC to end of visor_close to be nicer, as the final write
 430        message can sleep.
 431
 432 (11/12/2000) gkh
 433        Fixed bug with data being dropped on the floor by forcing tty->low_latency
 434        to be on.  Hopefully this fixes the OHCI issue!
 435
 436 (11/01/2000) Adam J. Richter
 437        usb_device_id table support
 438
 439 (10/05/2000) gkh
 440        Fixed bug with urb->dev not being set properly, now that the usb
 441        core needs it.
 442
 443 (09/11/2000) gkh
 444        Got rid of always calling kmalloc for every urb we wrote out to the
 445        device.
 446        Added visor_read_callback so we can keep track of bytes in and out for
 447        those people who like to know the speed of their device.
 448        Removed DEBUG #ifdefs with call to usb_serial_debug_data
 449
 450 (09/06/2000) gkh
 451        Fixed oops in visor_exit.  Need to uncomment usb_unlink_urb call _after_
 452        the host controller drivers set urb->dev = NULL when the urb is finished.
 453
 454 (08/28/2000) gkh
 455        Added locks for SMP safeness.
 456
 457 (08/08/2000) gkh
 458        Fixed endian problem in visor_startup.
 459        Fixed MOD_INC and MOD_DEC logic and the ability to open a port more
 460        than once.
 461
 462 (07/23/2000) gkh
 463        Added pool of write urbs to speed up transfers to the visor.
 464
 465 (07/19/2000) gkh
 466        Added module_init and module_exit functions to handle the fact that this
 467        driver is a loadable module now.
 468
 469 (07/03/2000) gkh
 470        Added visor_set_ioctl and visor_set_termios functions (they don't do much
 471        of anything, but are good for debugging.)
 472
 473 (06/25/2000) gkh
 474        Fixed bug in visor_unthrottle that should help with the disconnect in PPP
 475        bug that people have been reporting.
 476
 477 (06/23/2000) gkh
 478        Cleaned up debugging statements in a quest to find UHCI timeout bug.
 479
 480 (04/27/2000) Ryan VanderBijl
 481        Fixed memory leak in visor_close
 482
 483 (03/26/2000) gkh
 484        Split driver up into device specific pieces.
 485
 486-----------------------------------------------------------------------
 487pl2303.c Change Log comments:
 488
 489 2002_Mar_26 gkh
 490        allowed driver to work properly if there is no tty assigned to a port
 491        (this happens for serial console devices.)
 492
 493 2001_Oct_06 gkh
 494        Added RTS and DTR line control.  Thanks to joe@bndlg.de for parts of it.
 495

 497        Added break support.
 498
 499 2001_Aug_30 gkh
 500        fixed oops in write_bulk_callback.
 501
 502 2001_Aug_28 gkh
 503        reworked buffer logic to be like other usb-serial drivers.  Hopefully
 504        removing some reported problems.
 505
 506 2001_Jun_06 gkh
 507        finished porting to 2.4 format.

 715
 716 0.2 (01/30/2000) greg kroah-hartman
 717        Milestone 1 release.
 718        Device is found by USB subsystem, enumerated, fimware is downloaded
 719        and the descriptors are printed to the debug log, config is set, and
 720        green light starts to blink. Open port works, and data can be sent
 721        and received at the default settings of the UART. Loopback connector
 722        and debug log confirms this.
 723
 724 0.1 (01/23/2000) greg kroah-hartman
