Bus 001 Device 010: ID 04b8:1122 Seiko Epson Corp. ET-2600 Series
Tried adding this rule to /usr/lib/udev/rules.d/60-libsane.rules, but
this didn't help:
ATTRS{idVendor}=="04b8", ATTRS{idProduct}=="1122",
ENV{libsane_matched}="yes"
However the rule does make it so uaccess is run:
$ sudo udevadm test $(udevadm info --query=path --name=/dev/bus/usb/001/010)
2>&1
This program is for debugging only, it does not run any program
specified by a RUN key. It may show incorrect results, because
some values may be different, or not available at a simulation run.
