Third party backend, not something the SANE Project is involved in. You
should contact the `lexmake_nscan` developers for support.

Whether it's in issue I cannot answer, but I can tell you that backends
are free to use whatever suits their fancy after the `$backend:` bit. I
seem to remember having seen `$backend:usb:$VID:$PID` where the $VID and
$PID refer to USB vendor and product IDs, respectively.
The part after the `$backend:` bit is processed by the backend itself,
so really anything goes.
Hope this helps,
