Could you have tried the following patch:
Lookup the following piece of code in /sys/dev/usb/umass.c :
static void
umass_t_bbb_data_read_callback(struct usbd_xfer *xfer)
{
struct umass_softc *sc = xfer->priv_sc;
u_int32_t max_bulk = (UMASS_BULK_SIZE -
(UMASS_BULK_SIZE % xfer->max_packet_size));
USBD_CHECK_STATUS(xfer);
tr_error:
if (xfer->error == USBD_CANCELLED) {
umass_tr_error(xfer);
} else {
umass_transfer_start(sc, UMASS_T_BBB_DATA_RD_CS);
}
return;
tr_transferred:
Change:
umass_transfer_start(sc, UMASS_T_BBB_DATA_RD_CS);
Into:
umass_transfer_start(sc, UMASS_T_BBB_STATUS);
Then recompile the umass module and/or the kernel, depending on how you load
umass.
Then try to read from your umass device.
