I just bought an Epson V500 photo flatbed scanner….works great with Ubuntu x64….the 64 bit drivers in .deb pkgs can be scored here (click the ‘English’ button, then scroll to the bottom and pick your epson scanner):
http://www.avasys.jp/lx-bin2/linux_e/scan/DL1.do
install both debs, in the order listed:
DEB 64bit package [libltdl7] (for Ubuntu 8.10 or later)
iscan_2.21.0-6.ltdl7_amd64.deb
iscan-plugin-gt-x770_2.1.1-2_amd64.deb
A scanner program, Image Scan!, will show under Graphics in your gnome menu; launch it and scan away !
