Hi,
Try removing the following two pieces of code from sys/dev/usb/serial/ulpt.c:
/* clear stall first */
mtx_lock(&sc->sc_mtx);
usbd_xfer_set_stall(sc->sc_xfer[ULPT_BULK_DT_RD]);
mtx_unlock(&sc->sc_mtx);
/* clear stall first */
mtx_lock(&sc->sc_mtx);
usbd_xfer_set_stall(sc->sc_xfer[ULPT_BULK_DT_WR]);
mtx_unlock(&sc->sc_mtx);
Then recompile the kernel or just the ulpt module if you load it.
