well, ok now, but there is still something under the hood!
my guess is that the udev update change introduced by Scott James doesn't
fully refresh the udev rights.
I've not taken the time to validate it though, so mea culpa.
the result is basically that if you don't unplug/replug your device or
reboot your system after nut installation, the udev rule is not applied.
I'll try to check that tomorrow, and make some more progress on 2.4.1-4,
which will be a major Debian update.
