[sane-devel] Acer ScanPrisa 640S: "Error during device I/O"

Wed Aug 8 18:00:59 BST 2001

Hi there,

Already a couple of months ago I bought an
"Acer ScanPrisa 640S" SCSI-Scanner. I managed to 
get it work with SANE, a older version of SANE that was
not splitted up in two pieces like it is now.

Now, after I installed SuSE 7.2 from scratch, I'm
not able to get the scanner work again, trying with
SANE Version 1.0.5. 
It ends up with an "Error during device I/O".

I attached three log files to this email containing a
part of "/var/log/messages" and the ouput
of 
  "scanimage -L" 
and 
  "scanimage --test --device=snapscan:/dev/scanner"

Somebody there that can give me a hint/help to get
the scanner working again ?

Thanks, 
 Andreas
