I'm not that familiar with linux device naming, but does it show up as a
serial(tty) device, or a hid one?

If it shows up as a hid device but uses a serial protocol, maybe we need
to rethink a few details on how nut communicates with the UPSes?

Since it seems the manufacturers are quite adept at re-inventing wheels
with odd shapes, maybe we need to split up things in protocol and
interface blocks, i.e.

<hardware>
  <devicetypewrapper>
    <protocol>
      nut
    </protocol>
  </devicetypewrapper>
</hardware>

This way we may be able to quirk in new devices by mapping a protocol to
the device wrapper?

If my reading-skills are somewhat sane, the usb-hid-ups driver basically
behaves this way already and contains several subdrivers. To me this
looks like the way forward.

Splitting it this way would make handling OS changes (and porting to
OSes) easier as well, since the internal protocol part can remain intact...

Just my €0.02 on the thing.
