Which version of SANE do you use (scanimage --version)?

What's the output (as root) of 
"SANE_DEBUG_EPSON=255 scanimage -L"?
If there is no debug output at all, either your installation of
sane-backends is broken (reinstall sane-backends!) or "epson" is
missing in /etc/sane.d/dll.conf.

That's video4linux, so it's not relevant directly. When you want to
know what char-major-something means, have a look at the
Documentation/devices.txt in the Linux kernel source code.
