I got a deal on an Epson Perfection V330 scanner. It runs great in Windows 7 with the voluminous amount of software on the install CD. I hoped that it would work out of the box with Debian Squeeze. No such luck. Sane/Xsane doesn’t recognize it (although it's in the dmesg).
I downloaded, unpacked and installed the driver and scanning software from Avasys, and with a reboot I was able to scan from my Debian Squeeze laptop.
It all works great. Thus far I've only used the Image Scan! software (yep, the name has an
! in it), which does work fairly well by the way.
I imagine these same packages would work for Ubuntu. There are also packages for Mint, Mandriva, CentOS, Fedora, PCLinuxOS and a few others.
You would think that scanners, especially those by companies such as Epson, would either work out of the box or have packages within the Debian (or Ubuntu) repos, if only in non-free. Guess not.
But since the solution was fairly easy to come by, I'm accepting (and now using) it.
