  SVN rev 208221 on 2010-05-17 23:45:31Z by thompsa
  
  MFC r208008
  
   If a USB device is suspended and a USB set config request is issued when the
   USB enumeration lock is locked, then the USB stack fails to resume the device
   because locking the USB enumeration lock is part of the resume procedure. To
   solve this issue a new lock is introduced which only protects the suspend and
   resume callbacks, which can be dropped inside the usbd_do_request_flags()
   function, to allow suspend and resume during so-called enumeration operations.
