Fedora 9 x86_64 and Epson Perfection 3170
On Fedora 8 x86_64 I got the proprietary Epson scanner software
to work by restricting the sane packages to i386 and the following:
However on Fedora 9 x86_64 this trick didn't work, the iscan gui came
up but clicking on "Preview" result in a "warming up" status message,
but also, "Could not send command to scanner. Check the scanner's
status" and there was no preview scan.
I found that by commenting out the "epson", "epson2" and "hpaio" lines
in /etc/sane.d/dll.conf that the iscan/scanner starts working.
Hope this helps someone else out there.
