USB fixes for 3.19-rc5

Browse Source 
Here is a bunch of USB fixes for 3.19-rc5.
 
 Most of these are gadget driver fixes, along with the xhci driver fix
 that we both reported having problems with, as well as some new device
 ids and other tiny fixes.
 
 All have been in linux-next with no problems.
