    SUMMARY: scanimage gives:
            scanimage: open of device hp:/dev/scanner failed: Invalid argument
    and no devices are found.

    -------------------------------------------------------------
    Hi

    We have an old HP IIp scanner.

    Linux (Red Hat 6.0) sees the scanner on boot:
    ---------------------------------------------
            cat /proc/scsi/scsi

            Attached devices:

    -------------------------------------------------------

    We also have a polaroid slide scanner (as you can see from the list
    above) and that works fine with vuescan.

    However, with sane 1.0.2 installed,
            scanimage --help -d hp:/dev/scanner

    gives me this:

    ---------------------------------------------
            Usage: scanimage [OPTION]...

            Start image acquisition on a scanner device and write PNM image data
            to
            standard output.

            -b, --batch=FORMAT working in batch mode
            -d, --device-name=DEVICE use a given scanner device
            -h, --help display this help message and exit
            -L, --list-devices show available scanner devices
            -T, --test test backend thoroughly
            -v, --verbose give even more status messages
            -V, --version print version information
            scanimage: open of device hp:/dev/scanner failed: Invalid argument
            Type ``scanimage --help -d DEVICE'' to get list of all options for
            DEVICE.

            List of available devices:
    ---------------------------------------------

    There is NO list of available devices.

    BTW, I have set
            SANE_DEBUG_HP=255
    and
            SANE_DEBUG_SANEI_SCSI=255

    before running the above commands, **but I get no debug output** !!

    Weird ?

    I don't know whether our file system config has upset it - we use the
    Eidelon File System Standard, so src and binaries/libs are in /store/p1, with
    links across the system to /share/links/linux/lib,
    /share/links/linux/bin etc. All our other programs which use this
    system work OK.

    dll.conf looks like this:

            hp:/dev/scanner
            abaton
            agfafocus
            apple
            avision
            artec
    etc etc.

    hp.conf looks like this:

            /dev/scanner

    (I also tried it like this:
            scsi HP
            /dev/scanner
    ).

    Also, /dev/scanner is a link to /dev/sgc, and I've tried using that
    instead of /dev/scanner - no joy.

    find/scanner gives this:

            find-scanner: found processor "HP C1790A 3226" at device /dev/scanner
            find-scanner: found processor "HP C1790A 3226" at device /dev/sg2
            find-scanner: found scanner "POLAROID 35MM 1.00" at device /dev/sg3
            find-scanner: found processor "HP C1790A 3226" at device /dev/sgc
            find-scanner: found scanner "POLAROID 35MM 1.00" at device /dev/sgd

    Any thoughts ?

    Regards,
    Pete
