Maybe your device isn't fully supported in the backport?
http://www.linux-usb.org/ has a 'device support' section. Or
http://www.qbik.ch/usb/devices/ has the working devices list.
The second list doesn't show any working Epson 636u device, although
there are some Epson Perfection 12xx, 1640SU and Perfection 640U
devices.
