<P>Yeah, its far from an ideal solution. But it does have two things
|
|
<BR>
|
|
going for it. 1) It may keep people from having a 8 1/2 x 11 paper
|
|
<BR>
|
|
weight on their desk if sane-1.0.3 snapscan driver doesn't work for
|
|
<BR>
|
|
them. (ie. like me) 2) Since I have been unable to come up with docs
|
|
<BR>
|
|
on the main controlling ASIC of the scanner its very useful to
|
|
<BR>
|
|
compare working code with none working code.
|
|
<BR>
|
|
<P>I do plan to help debug these lockups and push the latest drivers as
|
|
<BR>
|
|
the solution but in the mean time I do have the occasional scans that
|
|
<BR>
|
|
I would like to perform and so far only sane-1.0.1 works reliably
|
|
<BR>
|
|
for me.
|
|
<BR>
|
|
<P>Here is a dumb question. Anyone have docs on any of the compatible
|
|
<BR>
|
|
scanners? I sent an email to Acer supported which appears to have
|
|
<BR>
|
|
gone to the standard /dev/null. I attempted to find an AFGA contact
|
|
<BR>
|
|
but was unable to from their web page. There is public docs on the
|
|
<BR>
|
|
Analog Devices AD9822 scanner chip that my Acer 640BU uses but the
|
|
<BR>
|
|
main ASIC is labeled as "AP7107U" and I'm unable to find anything on
|
|
<BR>
|
|
on it.
