Thanks to Tridge's findstatic.pl script for helping find these.

I've received the following report which indicates that the Sony Clie needs
the US_FL_FIX_INQUIRY flag set.

http://bugs.debian.org/243650

This patch imports the changes that David Brownell has made to the
device-reset functions in his gadget-2.6 tree.  Once these ongoing
troubling questions about locking are settled, I'll add support for the
"descriptors changed" case.

Only one aspect of it is notable: The CPiA USB
driver calls usb_driver_release_interface() during its disconnect()
routine.  That doesn't appear to be necessary, since it didn't call
usb_driver_claim_interface() beforehand and since the interface will be
released automatically when disconnect() returns.

Greg and Pete, here's the patch.  It's possible that this entry could be
combined with the previous one, but until we know definitely they should
be kept separate.

This patch allocates a temporary array from the heap instead of from the
kernel's stack in usb_set_configuration().  It also updates a few
comments.  Please apply.

this is the second version of the patch to add support for eGalax Touchkit USB
touchscreen. changes since last patch:
- fixed the bug in open, found by oliver neukum
- renamed driver from touchkit.c to touchkitusb.c (since the thing also exists
  as RS232, PS/2 and I2C)
- some minor coding style updates

This adds another ax8817x device to "usbnet".

g_serial.ko can't be load as module because "debug" is only
defined if G_SERIAL_DEBUG is defined, but "debug" is referenced
in MODULE_PARM().

below is a trivial patch which fixes the PXA gadget define
in drivers/linux/usb/gadget/gadget_chips.h

Everywhere CONFIG_USB_GADGET_PXA2XX is used, except in that file, which
bites obviously ...


Fix define for PXA UDC.

Info was from Adriaan de Groot <adridg@cs.kun.nl>

The attached patch for the 3M Touch Systems Capacitive controller. (again)

Quick list of changes:

   * decrease mtouch->open counter in the event of a urb submission
     failure

The changes are due to comments Oliver Neukum's comments on the
touchkit.c driver.  Good catch!  Sorry I missed it.

This patch updates the USB IrDA driver to take into account that the
kernel may no longer store altsetting entries in numerical order.
The driver only needed one change; this was a simple matter of using the
entry corresponding to the altsetting that was just installed.

I didn't get around to doing real work on this until now, but finally
in the attachment there's my stab at bringing dsbr100 up to kernel 2.6.
I'm not really comfortable with the release callback issues (I've yet
to find some HOWTO-like documentation on this...) on the v4l side,
so I'd be grateful if you could have a look at it.  I've basically
tried to copy what stv680 does, which may or may not have been a
good idea (in particular see the comment above the disconnect
function).

I've used the opportunity for some code beautyfing, which of course
makes the patch a bit of a mess.  I hope you won't mind too much
-- as you can see, it would have been pretty messy anyway.

Here's what's in my tree to make dummy_hcd do suspend and
wakeup correctly ... that is, making its emulated root hub
and gadget work more like real ones.

It's easier to do this for fake hardware than the real stuff.
But real drivers tend to need very similar changes ... :)

- Dave

p.s. This does not depend on the suspend/resume patch.
      And it doesn't do "global" suspend (of root hub).

Hi Greg, if won't accept a BUG_ON, how about the following?

And change __inline__ to inline and get rid of an unused function
while at it.

here is the latest version 0.95 of the LEGO USB Tower driver against 2.6.6-rc3
which corrects a lot of problems in the version currently in the kernel,
most notably sleeping in interrupt context and improper locking.
Please apply.

It has been thoroughly tested with UHCI, OHCI and EHCI host controllers
using Lejos and NQC.  Firmware and program download, and with proper
modifications all communication protocols supported by Lejos work,
as well as firmware and program download and datalog upload in NQC.

Notes to application maintainers/protocol designers:

- Small modifications are needed in communication protocols because
  the tower tends to discard the first byte of transmissions.
  So for example LNP needs to send an extra byte like 0xff before
  the packet, and F7 handlers needs to cope with a lost 0x55.

- I suggest /dev/usb/legousbtower0 etc. as the standard device names.
  This puts it in the same place as the other USB devices and makes
  clear which driver is responsible for these devices.

This patch rejects URB submissions to suspended devices, so
that they don't get hardware-specific fault reports.  Instead,
they get the same code (-EHOSTUNREACH) for all HCDs.

It also fixes a minor problem with colliding declarations of
the symbol USB_STATE_SUSPENDED.

This patch lets gadget zero be more useful in testing usb suspend
and resume.  It prints messages on suspend() and resume(), and
supports an "autoresume=N" mode to wake the host after N seconds.

The Alcatel TD10 USB to Serial converter cable (for use with a Alcatel
OT 535 or 735(i) mobile phone) seems to be a repackaged Alcatel
version of the Prolific 2303 adapter.

And as such, simply adding its product/vendor id (0x11f7/0x02df) to
drivers/usb/serial/pl2303.c seems to be enough to make it work.

The USB core is changing the way interfaces and altsettings are stored.
They are no longer required to be in numerical order, and as a result,
simply indexing the interface and altsetting arrays won't work as
expected.

This patch for the st5481 takes these changes into account.  A simpler
approach would be to store a pointer to the struct usb_host_interface
rather than look it up repeatedly, but I'm not very familiar with this
driver and didn't want to attempt such an alteration.

This really needs to get fixed the proper way, by making the urb allocation
dynamic in the driver, instead of the hack it is currently doing...

Somehow I managed to send the wrong version. Here is a patch which fixes
that. (Remove a dev_info() which wasn't supposed to be there, and make sure
that everything is still consistent in the unlikely event that kmalloc()
fails). Just minor cleanups.

Yes, it's the right fix.  Greg, please merge the attached patch,
which will be needed on any big-endian system.

More functions and data that should be static.

Funny you should ask...

While writing those patches I noted a problem, that the USB device tree
can change while a process reading /proc/bus/usb/devices is traversing it,
leading to an oops when a pointer to a no-longer-existing child device is
dereferenced.  The ensuing discussion led to the conclusion that the
devices' ->serialize locks should be acquired, top-down, while going
through the tree.

That means changing the code that populates the devices file and changing
the code that adds and removes USB device structures.  This patch takes
care of the first part.  I'm delaying the second part because that section
of usbcore is still under change -- David Brownell's revisions have not
yet been fully integrated.

A similar change should be made to usb_find_device() and match_device() in
usb.c.  You may want to add that yourself.
