USB patches for 3.6-rc6 

Here are a number of USB patches, a bit more than I normally like this
 late in the -rc series, but given people's vacations (myself included),
 and the kernel summit, it seems to have happened this way.
 
 All are tiny, but they add up.  A number of gadget and xhci fixes, and a
 few new device ids.  All have been tested in linux-next.
