Ok. Can you try to register the scanner manually?

1. Attach your scanner and turn it on.

2. Run 'sane-find-scanner'. You should see something like

found USB scanner (vendor=0x04b8 [EPSON], product=0x0142 [EPSON Perfection V33/V330]) at libusb:002:006

(these are for my EPSON Perfection V33/V330, your output should be different)

3. From root run (via sudo)

iscan-registry --add interpreter usb 0x04b8 0x0142 /usr/lib/esci/libesci-<your-interpreter>

(replace "0x04b8 0x0142" and "libesci-interpreter-<your-interpreter>" with your data, there must be some interpreter that was installed with Epson packages)

4. Check if there is registration file, /var/lib/iscan/interpreter, with the following data

interpreter usb 0xXXXX 0xXXXX /usr/lib/esci/libesci-interpreter-<your-interpreter>

You can use

iscan-registry -r interpreter usb 0xXXXX 0xXXXX /usr/lib/esci/libesci-<your-interpreter>

to remove duplicate registrations.

5. Run 'iscan' to check if the scanner works.
