USB fixes for 4.6-rc3

Browse Source 
Here are some USB fixes and new device ids for 4.6-rc3.
 
 Nothing major, the normal USB gadget fixes and usb-serial driver ids,
 along with some other fixes mixed in.  All except the USB serial ids
 have been tested in linux-next, the id additions should be fine as they
 are "trivial".
