[sane-devel] epson 2450 scanner and firewire: wrong SCSI ID

[Dave W]

This was accidentally posted to the linux1394-users' list.  Sorry for the
accidental cross-posting, in case any of you on this list are on the other
as well.

Ed Hamrick, the Vuescan author, wrote to me and told me the
problem is the Japanese ID of my Epson Perfection 2450 Photo as follows:

"The problem you're having with SANE not recognizing
the 2450 is that it's using the Japanese product naming
(i.e. GT-XXXX) in the scsi inquiry string.  SANE doesn't
recognize this type of inquiry string, although it would be
trivial to add this.

I added support for this some time ago in VueScan.  You
can verify that the 2450 is working by downloading
VueScan from:

  http://www.hamrick.com/vsm.html"

I already had downloaded it but didn't think to try it.  It DOES work, so
if the problem is that the GT-XXXX product naming string is wrong, where
do we correct that?

Thank you!

Certainly!

Does this tell you anything?
