Hi,

Please try to do as follows

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, yours output should be different)

3. From root run (via sudo)

iscan-registry --add interpreter usb 0x04b8 0x0142 /usr/lib/esci/libesci-
interpreter-perfection-v600

(replace "0x04b8 0x0142" with your data)

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

interpreter usb 0xXXXX 0xXXXX /usr/lib/esci/libesci-interpreter-perfection-
v600

You can use

iscan-registry -r interpreter usb 0xXXXX 0xXXXX /usr/lib/esci/libesci-
interpreter-perfection-v600

to remove duplicate registrations.

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

Hope this helps.

Best regards,
Yuri
