USB: fix oops on disconnect in cdc-acm

2009-08-07T23:05:14+00:00

This patch fixes an oops caused when during an unplug a device's table
of endpoints is zeroed before the driver is notified. A pointer to
the endpoint must be cached.

this fixes a regression caused by commit
5186ffee2320942c3dc9745f7930e0eb15329ca6
Therefore it should go into 2.6.31

USB: storage: include Prolific Technology USB drive in unusual_devs list

2009-08-07T23:05:14+00:00

Add a quirk entry for the Leading Driver UD-11 usb flash drive.

As Alan Stern told me, the device doesn't deal correctly with the
locking media feature of the device, and this patch incorporates it.

Compiled, tested, working.

USB: ftdi_sio: add vendor and product id for Bayer glucose meter serial converter cable

2009-08-07T23:05:13+00:00

Attached patch adds USB vendor and product IDs for Bayer's USB to serial
converter cable used by Bayer blood glucose meters. It seems to be a
FT232RL based device and works without any problem with ftdi_sio driver
when this patch is applied. See: http://winglucofacts.com/cables/

USB: EHCI: fix counting of transaction error retries

2009-08-07T23:05:13+00:00

This patch (as1274) simplifies the counting of transaction-error
retries.  Now we will count up from 0 to QH_XACTERR_MAX instead of
down from QH_XACTERR_MAX to 0.

The patch also fixes a small bug: qh->xacterr was not getting
initialized for interrupt endpoints.

USB: EHCI: fix two new bugs related to Clear-TT-Buffer

2009-08-07T23:05:13+00:00

This patch (as1273) fixes two(!) bugs introduced by the new
Clear-TT-Buffer implementation in ehci-hcd.

	It is now possible for an idle QH to have some URBs on its
	queue -- this will happen if a Clear-TT-Buffer is pending for
	the QH's endpoint.  Consequently we should not issue a warning
	when someone tries to unlink an URB from an idle QH; instead
	we should process the request immediately.

	The refcounts for QHs could get messed up, because
	submit_async() would increment the refcount when calling
	qh_link_async() and qh_link_async() would then refuse to link
	the QH into the schedule if a Clear-TT-Buffer was pending.
	Instead we should increment the refcount only when the QH
	actually is added to the schedule.  The current code tries to
	be clever by leaving the refcount alone if an unlink is
	immediately followed by a relink; the patch changes this to an
	unconditional decrement and increment (although they occur in
	the opposite order).

USB: usbfs: fix -ENOENT error code to be -ENODEV

2009-08-07T23:05:13+00:00

This patch (as1272) changes the error code returned when an open call
for a USB device node fails to locate the corresponding device.  The
appropriate error code is -ENODEV, not -ENOENT.

USB: musb: fix the nop registration for OMAP3EVM

2009-08-07T23:05:13+00:00

OMAP3EVM uses ISP1504 phy which doesn't require any programming and
thus has to use NOP otg transceiver.

Cleanups being done:
	- Remove unwanted code in usb-musb.c file
	- Register NOP in OMAP3EVM board file using
	  usb_nop_xceiv_register().
	- Select NOP_USB_XCEIV for OMAP3EVM boards.
	- Don't enable TWL4030_USB in omap3_evm_defconfig

USB: devio: Properly do access_ok() checks

2009-08-07T23:05:12+00:00

access_ok() checks must be done on every part of the userspace structure
that is accessed. If access_ok() on one part of the struct succeeded, it
does not imply it will succeed on other parts of the struct. (Does
depend on the architecture implementation of access_ok()).

This changes the __get_user() users to first check access_ok() on the
data structure.

USB: pl2303: New vendor and product id

2009-08-07T23:05:12+00:00

I am submitting a patch for the pl2303 driver.  This patch adds support
for the "Sony QN-3USB" cable (vendor=0x054c, product=0x0437).  This USB
cable is a so-called data cable used to connect a Sony mobile phone to a
computer.  Supported models are Sony CMD-J5, J6, J7, J16, J26, J70 and
Z7.

I have used this patch with my Sony CMD-J70 for several days and I
haven't encountered any kernel/hardware issue.
