  Modified files:
    sys/dev/usb          usbdi.c 
  Log:
  Correct cache handling for xfer requests marked URQ_REQUEST: many (if not
  all uses) involve a read but usbd_start_transfer only does a PREWRITE; change
  this to BUS_DMASYNC_PREREAD | BUS_DMASYNC_PREWRITE as I'm not sure if any
  users do write+read.
