Merge tag 'usb-3.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb

Here are a bunch of USB patches for 3.3-rc1.

Nothing major, largest thing here is the removal of some drivers that
did not work at all.  Other than that, the normal collection of bugfixes
and new device ids.
Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
