First of all: it does seem wrong that SANE tries to use the snapscan
backend (see sane-snapscan(5) man page) with your scanner. Since it is
reported as a Epson scanner it should be using one of the epson
backends
(sane-epson(5) or sane-epson2(5) for the man pages).
Unfortunately, your scanner is also listed as not supported here:
http://sane-project.org/sane-mfgs.html

Try 'scanimage -L' to get SANE to check for scanners it recognizes.
see the man page scanimage(1) for more: 'man scanimage'.

Some scanners need to have their firmware uploaded every time they are
powered on.
The firmware is not distributed by SANE for obvious reasons. If you
have such a scanner, you will have to find and extract the firmware
file from the (Windows) driver / install yourself. (I had a SnapScan
scanner once, there was a SnapScan_XXX.bin file in a directory of the
windows install; this was the firmware so I just copied it and
configured SANE to use it)

Hope this helps a bit.
