[HowTo] Sane Scanner-Server with XSane Frontend

[corwin_x]

I did it exactly as your howto says, but without success - I get this from sane-find-scanner:

found USB scanner (vendor=0x04b8 [Language Error], product=0x083f [Language Error]) at libusb:001:002

scanimage -L :

No scanners were identified. If you were expecting something different,
check that the scanner is plugged in, turned on and detected by the
sane-find-scanner tool (if appropriate). Please read the documentation
which came with this software (README, FAQ, manpages).

I have an Epson DX 4400 scanner/printer combo, printing (somehow - printer mustn't be in standby mode, otherwise > printer shutdown) works...

EDIT:
here is the output of xinetd -d

EDIT 2
I made the xinetd + saned running (well, I'm so brilliant that I forgot to chmod +x the post-boot and other scripts), thus eliminated the problem in 1st EDIT, but outputs from sane-find-scanner and scanimage -L remains unchanged. I tried commenting the epson2 backend and using epson, but no improvement. Is there a compiled epkowa backend available?
