Hi,
The code is now:
static void
ulpt_start_read(struct usb_fifo *fifo)
{
DPRINTF("debugging ulpt.c: %s\n", "ulpt_start_read() skiped ULPT_BULK_DT_RD");
#if 0
struct ulpt_softc *sc = usb_fifo_softc(fifo);
usbd_transfer_start(sc->sc_xfer[ULPT_BULK_DT_RD]);
#endif
}
but it seems that ulpt_start_read() is never called:
