    Thanks for the pointer! There are lots of statements around, including one
    at the SANE website, that the 3200C isn't supported -- but the man page for
    sane-umax_pp specifically indicates that it is.

    However, I still can't get it going. I think I need to know the correct
    call on scanimage. Here's one thing I tried, with results:

    pwa@suillus:~> scanimage -d umax_pp:/dev/scanner
    [umax_pp_low] Found 0x18 expected 0x00 (umax_pp_low.c:4007)
    [umax_pp_low] Unexpected value for for register 0x0D, expected 0x00 or 0x40,
    got 0x18 ! (umax_pp_low.c:4078)
    [umax_pp_low] EPPRegisterRead, found 0xFF expected 0x0 (umax_pp_low.c:4164)
    scanimage: open of device umax_pp:/dev/scanner failed: Invalid argument

    I tried the same thing with /dev/null, /dev/lp0, and also with umax_pp:0X3BC
    (following the information in the "DEVICE NAMES" section of the manpage) with
    the same result in each case. I know the scanner is working because I can
    use it under Win4Lin. I tried calling scanimage both as a normal user and as
    root; that made no difference either.

    I looked in /proc for something that looked like IEEE 1284 probe information,
    but found nothing.

    And of course,

       scanimage -L

    tells me that that no scanners were identified.

    I expect I'm just missing the magic incantation.

    Many thanks -
