Hmmm, that means I would have to open up the computer and replace the
Acard card... Is this another case of a manufacturer with a
non-disclosure agreement with microsoft, etc. causing the Sane staff
to be unable to write software to operate it?   Or does the Acard go
by the standards, but has internal errors that microsoft allows for,
but strict Sane does not?

I suppose I could
1) fire up "win98" when I want to scan something. my current solution.
2) go the many kilometers into the big city to find the hardware to
make it work with linux.

if i had it working under linux, then i could contribute ideas,
comments to the sane project.

however, i am too lazy to leave my hilltop hideaway home.

is there any chance soon that someone will write software to help with
my acard, or is it too small a problem in terms of people affected?

does a linux solution seem near, or is it a harder problem like
winmodems?

if it is hopeless, tell me and I'll just fire up "win98" [a "frontend"
in my mind].
