Pete Zaitcev 0256839619 [PATCH] usbmon in 2.6.13: peeking into DMA areas
This code looks at urb->transfer_dma, maps the page and takes the data.
I am looking for volunteers to contribute architectures other than i386
or to develop an architecure-neutral API for it (or point me that it
was done already).

david-b@pacbell.net d0384200f6 [PATCH] ehci: add tt_usecs
This adds the field tt_usecs to ehci_qh and ehci_iso_stream, and sets it
appropriately when setting them up as periodic endpoints.  It records
the transation translator's think_time (added in last patch) plus the
downstream (i.e. low or full speed) bustime of the transfer associated
with each interrupt or iso frame, as calculated by usb_calc_bus_time.

David Brownell 090ffa9d0e [PATCH] USB: usbnet (9/9) module for pl2301/2302 cables
This wraps up the conversion of the "usbnet" driver structure, by
moving the Prolific PL-2201/2302 minidriver to a module of its own.
It also includes some minor cleanups to the remaining "usbnet" file,
notably removing that long changelog at the top.

Minor historical note:  Linux 2.2 first called the driver for
this hardware "plusb".

David Brownell 64e049102d [PATCH] USB: usbnet (8/9) module for RNDIS devices
This adds host-side RNDIS support to the "usbnet" driver, so Linux can talk
to various devices (often based on WinCE) that otherwise only Windows could
talk to.

Tested with little-endian Linux talking to a Linux-USB Ethernet/RNDIS based
peripheral.  This also includes updates from Eddie C. Dost <ecd@brainaid.de>
for big-endian SPARC Linux talking to a Nokia 9500 Communicator.

It's still marked as EXPERIMENTAL because this code is so young.  This
ought to let Linux to work with various cable modems that previously
would have been "Windows Only".

David Brownell 2e55cc7210 [PATCH] USB: usbnet (3/9) module for ASIX Ethernet adapters
This patch moves the ASIX AX8817x driver into its own file, just using
the "usbnet" infrastructure as a utility library.

 - As with "cdc_subset" this involved minor Kconfig/kbuild tweaks,
   moving code from one file to another, and exporting a few functions.

 - This includes updates from Jamie Painter to add (and use) a new hook
   to handle the different maximum transfer sizes for rx and tx sides.

 - Also from Jamie, some bugfixes:
    * MDIO byteorder (to address some PPC media negotiation problems);
    * Force alignment at key spots when using ax88772 framing (on some
      embedded hardware, the network stack will break otherwise);
    * Address some link reset problems.

It also makes this driver use the standard (5 seconds vs half second)
control timeouts used elsewhere in USB; and wraps a few lines before
the 80th column (which previously needed it).

David Brownell 38bde1d469 [PATCH] USB: usbnet (2/9) module for simple network links
This patch creates the first of several separate "minidriver" modules
for "usbnet".  This one handles only the very simplest hardware, which
can be handled almost entirely by the "usbnet" core.

    - Move device-specific bits into new "cdc_subset.c" driver,
      shrinking "usbnet" by a bunch;

    - Export the functions needed to support this minidriver
      (with EXPORT_SYMBOL_GPL);

    - Update Kconfig and kbuild accordingly.

This one handles about a dozen different device types, with the most
notable ones being Gumstix and most Linux-based PDAs (except Zaurus
running that ancient code from Sharp).

David Brownell f29fc25997 [PATCH] USB: usbnet (1/9) clean up framing
This starts to prepare the core of "usbnet" to know less about various
framing protocols that map Ethernet packets onto USB, so "minidrivers"
can be modules that just plug into the core.

  - Remove some framing-specific code that cluttered the core:

      * net->hard_header_len records how much space to preallocate;
        now drivers that add their own framing (Net1080, GeneLink,
	Zaurus, and RNDIS) will have smoother TX paths.  Even for
	the drivers (Zaurus, Net1080) that need trailers.

      * defines new dev->hard_mtu, using this "hardware" limit to
        check changes to the link's settable "software" mtu.

      * now net->hard_header_len and dev->hard_mtu are set up in the
        driver bind() routines, if needed.

  - Transaction ID is no longer specific to the Net1080 framing;
    RNDIS needs one too.

  - Creates a new "usbnet.h" header with declarations that are shared
    between the core and what will be separate modules.

  - Plus a couple other minor tweaks, like recognizing -ESHUTDOWN
    means the keventd work should just shut itself down asap.

The core code is only about 1/3 of this large file.  Splitting out the
minidrivers into separate modules (e.g. ones for ASIX adapters,
Zaurii and similar, CDC Ethernet, etc), in later patches, will
improve maintainability and shrink typical runtime footprints.

Alan Stern 3b4d7f7916 [PATCH] USB: Support unbinding of the usb_generic driver
This patch (as556) adds support for unbinding the usb_generic "driver".
That driver only binds to USB devices, as opposed to interfaces, and it
does nothing much besides marking which struct device's go with an
overall USB device plus providing suspend/resume methods.  Now that
users can unbind drivers at will using the sysfs "unbind" attribute, we
need a rational way of dealing with USB devices that are no longer under
full control of the USB stack.  The patch handles this by unconfiguring
the device, thereby removing all the interfaces and their associated
drivers and children.

Alan Stern b375a0495f [PATCH] USB: URB_ASYNC_UNLINK flag removed from the kernel
29 July 2005, Cambridge, MA:

This afternoon Alan Stern submitted a patch to remove the URB_ASYNC_UNLINK
flag from the Linux kernel.  Mr. Stern explained, "This flag is a relic
from an earlier, less-well-designed system.  For over a year it hasn't
been used for anything other than printing warning messages."

An anonymous spokesman for the Linux kernel development community
commented, "This is exactly the sort of thing we see happening all the
time.  As the kernel evolves, support for old techniques and old code can
be jettisoned and replaced by newer, better approaches.  Proprietary
operating systems do not have the freedom or flexibility to change so
quickly."

Mr. Stern, a staff member at Harvard University's Rowland Institute who
works on Linux only as a hobby, noted that the patch (labelled as548) did
not update two files, keyspan.c and option.c, in the USB drivers' "serial"
subdirectory.  "Those files need more extensive changes," he remarked.
"They examine the status field of several URBs at times when they're not
supposed to.  That will need to be fixed before the URB_ASYNC_UNLINK flag
is removed."

Greg Kroah-Hartman, the kernel maintainer responsible for overseeing all
of Linux's USB drivers, did not respond to our inquiries or return our
calls.  His only comment was "Applied, thanks."

the order of submission of this latest patch series -- even tho this has

This patch changes the reported SCSI revision level to 2 for all

reports a level of 3 or higher but then crashes when given a REPORT LUNS
command (for which support is supposed to be mandatory at those levels).
This shouldn't harm us, since it only matters for sparse LUNs and we
have separate ways of coping with that.

Matthew Dharm 26186ba77b [PATCH] USB Storage: close a race condition in disconnect near queuecommand
This patch started life as as534, and has been re-diffed against the latest
tree.

usb-storage has a small loophole, a window between the time queuecommand
accepts a new command and the time the control thread starts to execute
it.  If disconnect is called during that window, the driver won't cancel
the pending command -- we've been relying on the SCSI core to cancel it
for us during host removal.  But it's better for usb-storage to cancel
it;  this avoids races and reduces reliance on the SCSI core.
Fortunately cancelling these commands is easy to do; the key is to do it
_before_ calling scsi_remove_host.

Matthew Dharm 77f46328fb [PATCH] USB Storage: close a race condition in disconnect near probe
This patch started life as as533, and has been re-diffed against the
current tree.

Disconnect processing in usb-storage naturally divides into two parts:
one to quiesce the driver (make sure no commands are executing or
queued) and remove the host, and the other to deallocate all the USB and
non-USB resources.  This patch creates two subroutines to handle those
two parts.  Mostly it's just code movement, but there is one significant
change.  If the scsi-scanning thread fails to initialize but the host
has successfully been added, we need to quiesce the driver before
removing the host.  After all, it's possible that scanning could have
been initiated from somewhere else, such as userspace -- very low
probability, but it's easily handled by calling the new subroutine.

This patch started life as as531 from Alan Stern.  It has been rediffed
against the latest tree.

The SCSI people have deprecated the use of scsi_cmnd.serial_number for
anything other than printk.  Worse than that, the SCSI core doesn't
always increment the number (when the error handler is running, for
example).  So this patch creates a locally-stored value for use in
bulk-only tags.  The net result is a simplification, since we no longer
have to save & restore the serial_number value while autosensing.

Back out Axboe-style quasi-S/G and replace it with one command and
repeated URBs. This is similar to what usb-storage does, only instead
of a few URBs allocated together, one URB is reused.

Jens's idea was very nice, but it collapsed when I had to support
packet commads for CD burning. I cannot issue two or more packet
commands where application expected only one.

However, burning does not work completely yet. The cdrecord starts,
recognizes the device, then aborts without writing a TOC.

Pete Zaitcev 6c1eb8c1c3 [PATCH] USB: ub 3/3: death to ub_bd_rq_fn_1
When Al Viro saw the ub.c, he observed that it was a proof positive of
Linus not reading patches anymore: names like fo_ob_ar_ba_2 used to
cause serious fireworks. In my defence, any good scheme can be pushed
to the realm of absurd if pushed far enough.

Pete Zaitcev ba6abf1352 [PATCH] USB: ub 1/3: Axboe's quasi-S/G
This the quasi-S/G patch for ub as suggested by Jens Axboe at OLS and
implemented that night before 4 a.m. Surprisingly, it worked right away...
Alas, I had to skip some OLS partying, but it was for the good cause.
Now the speed of ub is quite acceptable even on partitions with small
block size.

The ub does not really support S/G. Instead, it just tells the block
layer that it does. Then, most of the time, the block layer merges
requests and passes single-segmnent requests down to ub; everything
works as before. Very rarely ub gets an unmerged S/G request. In such
case, it issues several commands to the device.

I added a small array of counters to monitor the merging (sg_stat).
This may be dropped later.

Kay Sievers fbf82fd2e1 [PATCH] USB: real nodes instead of usbfs
This patch introduces a /sys/class/usb_device/ class
where every connected usb-device will show up:

  tree /sys/class/usb_device/
  /sys/class/usb_device/
  |-- usb1.1
  |   |-- dev
  |   `-- device -> ../../../devices/pci0000:00/0000:00:1d.0/usb1
  |-- usb2.1
  |   |-- dev
  |   `-- device -> ../../../devices/pci0000:00/0000:00:1d.1/usb2
  ...

The presence of the "dev" file lets udev create real device nodes.
  kay@pim:~/src/linux-2.6> tree /dev/bus/usb/
  /dev/bus/usb/
  |-- 1
  |   `-- 1
  |-- 2
  |   `-- 1
  ...

udev rule:
  SUBSYSTEM="usb_device", PROGRAM="/sbin/usb_device %k", NAME="%c"
  (echo $1 | /bin/sed 's/usb\([0-9]*\)\.\([0-9]*\)/bus\/usb\/\1\/\2/')

This makes libusb pick up the real nodes instead of the mounted usbfs:
  export USB_DEVFS_PATH=/dev/bus/usb

Background:
  All this makes it possible to manage usb devices with udev instead of
  the devfs solution. We are currently working on a pam_console/resmgr
  replacement driven by udev and a pam-helper. It applies ACL's to device
  nodes, which is required for modern desktop functionalty like
  "Fast User Switching" or multiple local login support.

New patch with its own major. I've succesfully disabled usbfs and use real
nodes only on my box. With: "export USB_DEVFS_PATH=/dev/bus/usb" libusb picks
up the udev managed nodes instead of reading usbfs files.

This makes udev to provide symlinks for libusb to pick up:
  SUBSYSTEM="usb_device", PROGRAM="/sbin/usbdevice %k", SYMLINK="%c"

/sbin/usbdevice:
  #!/bin/sh
  echo $1 | /bin/sed 's/usbdev\([0-9]*\)\.\([0-9]*\)/bus\/usb\/\1\/\2/'

Andrew de Quincey 22af8878d2 [PATCH] USB: Prevent hid-core claiming Apple Bluetooth device on new G4 powerbooks
To recap: My new G4 powerbook has a bluetooth device that boots up in
what apppears to be a compatability mode - it looks exactly like an HID
keyboard/mouse device.

A special command sequence is sent to switch it into full bluetooth
mode. When this occurs the original HID device vanishes, and a new
(bluetooth HID) USB device appears on the bus with a different product
ID.

The original thread is here:
http://sourceforge.net/mailarchive/message.php?msg_id=12532263

The attached patch adds the device to the hid-core quirks so that
hid-core ignores it.

Ian Abbott e6ac4a40e5 [PATCH] USB ftdi_sio: New IDs for ELV, Xsens and Falcom products
This patch for the ftdi_sio driver adds a bunch of new devices and fixes
an incorrect PID:

o Fix PID for ELV UO100 (the PID was in fact for ELV UR100).
o Add PID ELV UR100 (see above) and ELV ALC 8500 Expert.
o Add a whole bunch of other PIDs for ELV USB devices, commented out for
   now as they may be used by other drivers eventually.  (Christian Abt
   of ELV.de submitted a full list of devices including an indication of
   which set of drivers are used by default in the MS Windows world.  We
   decided to comment out the devices that use FTDI's D2XX Windows
   drivers by default.)
o Add PIDs for eight devices from Xsens Technologies BV (submitted in a
   patch against 2.6.12.2 by Patrick Riphagen).
o Add PID for Falcom Samba GPRS modem (submitted by Sebastian Schubert).

This trivial patch makes pl2303 driver work correctly with pl2303HX chip.
Apparently some bug in HX version of pl2303 makes the chip loose some
transmitted bytes or stop working at all after reception of
USB_REQ_CLEAR_FEATURE mesage. Logs generated by UsbSnoop application reveal
that windows driver does not send this type of messages to the converter.
