By the way, the devices entries start with "T:" (topology). So the
first three lines are from a different device and some lines are
missing.

If sane-find-scanner finds the scanner, it's also found by the kernel.
If it was found before you added the options entry to
/etc/modules.conf, that entry wasn't necessary.

I'm not sure, if it works without the "0x" (for hexadecimal numbers).
Try

options scanner vendor=0x04b8 product=0x0110

If it doesn't work, the exact text may be interesting (maybe it's in
/var/log/messages?)

Did you configure the epson backend? See man sane-epson and
/etc/sane.d/epson.conf. Probably it's enough to uncomment
"usb /dev/usb/scanner0" in that file.
