Merge tag 'usb-3.10-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb

Pull USB fixes from Greg Kroah-Hartman:
 "Here are a number of tiny USB bugfixes / new device ids for 3.10-rc2

  The majority of these are USB gadget fixes, but they are all small.
  Other than that, some USB host controller fixes, and USB serial driver
  fixes for problems reported with them.

  Also hopefully a fixed up USB_OTG Kconfig dependancy, that one seems
  to be almost impossible to get right for all of the different
  platforms these days."
