Hi Gerhard,
Thanks for your help. For what it's worth, the SANE-version is 1.0.3 and
the driver version is 0.36-36 . I still get the message about "unresolved
symbols" and I have no idea how to determine which symbols are
missing.
Now the EMBARRASSING part. The message:
"Device or resource busy" went away when I noticed the scanner was
unplugged and plugged it in. After that I was able to load the module and
use "scanimage" to scan a photo. However, at this point it scans only the
area where transparencies are placed to be scanned. So far Gimp hasn't
been able to find the scanner, so I guess when I get that sorted out, I'll
be able to adjust the image area, etc. Since the "unresolved
modules" messages persist, I've appended the messages I get in
/var/log/messages that appear related to the scanner. Maybe they'll throw
some light on the "unresolved symbols question." Meanwhile, the scanner
seems to work after a fashion whatever the symbols problem may be. Thanks
for your help, and especially for the driver.
John
