Okay, let's compare.  I have

/usr/local/etc/sane.d/epson.conf
# WB
usb 0x04b8 0x010a

/etc/devfs.conf
perm    xpt0    0660

/etc/devfs.rules
# WB
[localrules=10]
add path 'ugen*' mode 0660 group operator
add path 'usb/*' mode 0660 group operator
add path 'xpt*' mode 0660 group operator

Maybe that ugen entry is important.
