I have the epson 2480
I found the bin file I needed on the driver disc and copied it to my webspace below http://www.morganstorey.com/stuff/Esfw41.bin
I have followed the instructions and get the below

# scanimage -L
device `snapscan:libusb:005:003' is a EPSON EPSON Scanner flatbed scanner

I can now get xsane working, and scanimage -T seems to work, but it doesn't scan. Xsane just shows a slightly bluey blurred page as a preview and a finished product.
