Thanks, It turned out that i had to download the firmware from:
and place it in /usr/share/sane/gt68xx
. afterwards i tried to scan, Xsane opened up, did a scan, but the scan came out blurred in a way, not clear, perhaps it is just a matter of configuring it? i don't know. perhaps i should update the software to a later version? [as i mentioned above, mine is version xsane-0.996]
is there a download for Debian/Ubuntu?
Thanks for any help
