    Hi,

    Success! I downloaded a fresh copy of sane-1.0.3 and the latest snapscan
    drivers, and dropped them in to sane-1.0.3/backend. First I compiled them
    as-is, and linked xscanimage as a gimp plug-in, and was able to preview in
    color, and scan in color up to 300 dpi. Next, I tried changing line 90 in
    the snapscan.h file
    from {"FlatbedScanner_4", VUEGO310S}
    to {"FlatbedScanner_4", VUEGO610S},

    since as I mentioned, the scanner is really 600 DPI even though the Vendor
    string is "FlatbedScanner_4".
    Recompiled and installed, and the scanner now scans up to 600 DPI!

    Interesting to note that the dropdown menu in xscanimage for resolution has
    choices up to 9600 DPI, but at higher resolutions, xscanimage hangs, and
    uses 90% cpu. Actually, at 1200 DPI, I got one scan, but in the horizontal
    dimension, the image was scrunched up on the left and there were Red Green
    and Blue stripes in a black field on the right side.

    Anyway, it looks great so far, thanks!

    Next issue is to get 30 bit color depth. I have not tried to compile Xsane
    with the new backend yet. What are my chances there?
