    I didn't even know that the 3191 is supported by Linux. Which driver did you
    use? Probably this driver is 2.4 only, isn't it?

    For the older (non-PCI) SCSI adapters from Mustek interrupt was not
    supported by the Linux driver. However, it is possible to turn on usleeps in
    the driver to get better interactive performance. I don't know if something
    like this works for the 3191, too. Some information about this is on my web
    page (http://hmg.home.pages.de/sane/trouble.html).

    I don't know the second SCSI adapter.

    The freezing of the computer occurs as long as the driver waits for data.
    This period is esecially long after the "start_scan" command, when the
    scanner does positioning and calibration.

    You may do "export SANE_DEBUG_MUSTEK=5" and after that "scanimage -L". Look
    for the firmware version number. If this is anything other than 1.00 or 1.01
    please send me the full debug output.

    Bye,
