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.
