Hi,
I did:
# kldunload ulpt.ko
# kldload modules/usb/ulpt/ulpt.ko
# sysctl hw.usb.ulpt.debug=15
hw.usb.ulpt.debug: 0 -> 15
now I power-cycled the printer, let it print the self test page, plug'ed
in the cable into the printers parallel port, plug'ed in the USB end
into the laptop, and:
Run the command _before_ plugging the printer cable.
No change, log is:

Hi,
Try to comment out starting of bulk read transfers:
static void
ulpt_start_read(struct usb_fifo *fifo)
{
#if 0
struct ulpt_softc *sc = usb_fifo_softc(fifo);
usbd_transfer_start(sc->sc_xfer[ULPT_BULK_DT_RD]);
#endif
}
