Try using the “epson” backend instead of “epson2”; put the line
“usb 0x04b8 0x0131” in /usr/local/etc/sane.d/epson.conf.

Regarding permissions, on my system I created a group named "usb" of which I'm
a member. To give me access to USB devices, I put the following in
/etc/devfs.rules;

    [myrules=10]
    add path 'da*' mode 0660 group usb
    add path 'msdosfs/*' mode 0660 group usb
    add path 'usb/*' mode 0660 group usb
    add path 'ugen*' mode 0660 group usb

This ruleset is activated in /etc/rc.conf;

   devfs_system_ruleset="myrules"


Hope this helps,

Roland
