yup, give us more details on your nut version, and send back the
driver debug trace, Ie:
$ /path/to/powercom -DDDDD -a <upsname>
after having stopped the previous driver instance.

Note that we've add some improvements in 2.6.1 that you're probably missing.
So it would be better to first update nut, then do some more testing.
