    Hi there. I've been working with Karl Kremer for a few days and we're
    stuck. I've got everything seemingly set up right with the kernel and
    USB and sane. I've got the kernel version 2.2.14 with the 2.3.39 USB
    backport, I've got sane-1.0.2 and the 2000/03/27 epson backend (for
    sure). Anyways after turning debug info on and doing a scanimage
    --list-devices, i get nothing. For a scanimage --help -d epson i get :

    ------------------(cut)-------------------

    >/usr/local/bin/scanimage --help -d epson
    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
    [sanei_init_debug]: Setting debug level of epson to 255.

    And that's it.

    Here's my /proc/dev/bus/usb/device :

    ------------------(cut)-------------------

    I have the scanner module loaded with the right params.

    Any ideas? Any more details I can post to help debug this?

    Thanks.
