 I tried this (advice of "Hans Petter Selasky" <hselasky@c2i.net>)
 and it did not work:
 
 ----------------------------
 
 1) add the following to umass.c before "Static int
 umass_match_proto":
 
 static void
 umass_dummy_callback(usbd_xfer_handle xfer, usbd_private_handle
 priv,
                         usbd_status err)
 {
         return;
 }
                   
 static void
 umass_init_ucr(struct umass_softc *sc)
 {
         usbd_xfer_handle xfer;
 
         xfer = usbd_alloc_xfer(sc->sc_udev);
  
         if(!xfer) return;
 
         usbd_setup_xfer(xfer, sc->bulkout_pipe, NULL,
                 "\xec\x0a\x06\x00$PCCHIPS",
                 sizeof("\xec\x0a\x06\x00$PCCHIPS")-1,
                 0,
                 USBD_DEFAULT_TIMEOUT, umass_dummy_callback);
 
         usbd_sync_transfer(xfer);
 
         usbd_free_xfer(xfer);
         return;
 }
 
 2) and where you find the function umass_init_shuttle called, add
 umass_init_ucr(sc):
 
         if (sc->quirks & SHUTTLE_INIT)
                 umass_init_shuttle(sc);
 
         umass_init_ucr(sc);
 
 3) I am not sure if the string is right.
 
 ------------------------
 
 It's probably the trick beeing applied wrongly.
 
 You could try to change:
 
         usbd_setup_xfer(xfer, sc->bulkout_pipe, NULL,
                 "\xec\x0a\x06\x00$PCCHIPS",
                 sizeof("\xec\x0a\x06\x00$PCCHIPS")-1,
                 0,
                 USBD_DEFAULT_TIMEOUT, umass_dummy_callback);
 
 into:
 
         usbd_setup_xfer(xfer, sc->bulkout_pipe, NULL,
                
 "\xec\x0a\x06\x00$PCCHIPS\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0",
                 UMASS_BBB_CBW_SIZE,
                 0,
                 USBD_DEFAULT_TIMEOUT, umass_dummy_callback);
 
 though it doesn't work with my cardreader, it might work with
 yours.
