Merge tag 'usb-3.8-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb

Pull USB fixes from Greg Kroah-Hartman:
 "Here are a few tiny USB fixes for 3.8-rc6.

  Nothing major here, some host controller bug fixes to resolve a number
  of bugs that people have reported, and a bunch of additional device
  ids are added to a number of drivers (which caused code to be deleted
  from the usb-storage driver, always nice)"
