ok, finally have gotten my scanner to cooperate with my scsi hard drive so
i can go back to getting this thing to work. i have checked what you just
said and i am able to get greyscale images less than 64k to scan in ok. i
tried a color image at 59.9k and the top half of it was fine, but then it
got worse towards the bottom. if you'd like to see i can send you some of
these. i should probably note that i'm basically going blind because the
preview in xscanimage/xsane isnt showing me much. i can choose pretty much
any section which is <64k an it will get at least part of it scanned in
ok. very small scans (~15-20k) seem to come out great.

checked that and it doesnt find anything. i also did a

diff /usr/src/linux/include/scsi/sg.h /usr/include/scsi/sg.h

which i saw someone else mention and there was no difference.

if you have any other suggestions, just let me know. i should be able to
pick at this now. let me konw if you'd like to see some samples of what
i'm getting in as well as what the previews are looking like. thanks,
