USB: accept some invalid ep0-maxpacket values

2011-01-06T23:08:26+00:00

commit 56626a72a47bf3e50875d960d6b5f17b9bee0ab2 upstream.

A few devices (such as the RCA VR5220 voice recorder) are so
non-compliant with the USB spec that they have invalid maxpacket sizes
for endpoint 0.  Nevertheless, as long as we can safely use them, we
may as well do so.

This patch (as1432) softens our acceptance criterion by allowing
high-speed devices to have ep0-maxpacket sizes other than 64.  A
warning is printed in the system log when this happens, and the
existing error message is clarified.

USB: opticon: Fix long-standing bugs in opticon driver

2011-01-06T23:08:25+00:00

commit 97cd8dc4ca9a1a5efb2cc38758e01492e3b013e2 upstream.

The bulk-read callback had two bugs:
a) The bulk-in packet's leading two zeros were returned (and the two last
   bytes truncated)
b) The wrong URB was transmitted for the second (and later) read requests,
   causing further reads to return the entire packet (including leading
   zeros)

USB: disable endpoints after unbinding interfaces, not before

2011-01-06T23:08:25+00:00

commit 80f0cf3947889014d3a3dc0ad60fb87cfda4b12a upstream.

This patch (as1430) fixes a bug in usbcore.  When a device
configuration change occurs or a device is removed, the endpoints for
the old config should be completely disabled.  However it turns out
they aren't; this is because usb_unbind_interface() calls
usb_enable_interface() or usb_set_interface() to put interfaces back
in altsetting 0, which re-enables the interfaces' endpoints.

As a result, when a device goes through a config change or is
unconfigured, the ep_in[] and ep_out[] arrays may be left holding old
pointers to usb_host_endpoint structures.  If the device is
deauthorized these structures get freed, and the stale pointers cause
errors when the the device is eventually unplugged.

The solution is to disable the endpoints after unbinding the
interfaces instead of before.  This isn't as large a change as it
sounds, since usb_unbind_interface() disables all the interface's
endpoints anyway before calling the driver's disconnect routine,
unless the driver claims to support "soft" unbind.

This fixes Bugzilla #19192.  Thanks to "Tom" Lei Ming for diagnosing
the underlying cause of the problem.

USB: option: Add more ZTE modem USB id's

2011-01-06T23:08:24+00:00

commit ecfa153ef616b901e86d9a051b329fcda7a6ce7b upstream.

There are lots of ZTE USB id's currently not covered by usb/serial. Adds them,
to allow those devices to work properly on Linux.

While here, put the USB ID's for 0x2002/0x2003 at the sorted order.

This patch is based on zte.c file found on MF645.

PS.: The ZTE driver is commenting the USB ID for 0x0053. It also adds, commented,
an USB ID for 0x0026.

Not sure why, but I think that 0053 is used by their devices in storage mode only.
So, I opted to keep the comment on this patch.
