  Log:
  SVN rev 208008 on 2010-05-12 22:42:35Z by thompsa
  
  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.
