first, have you rebuilt from nut source or deb source?
if you've gone for #1, you should have prefered to backport the 2.4.1
packages in jaunty to get the best integration...

this might be due to:
- the missing udev rule file in /etc/udev/rules.d (52-nut-usbups.rules),
- or its application. I've noticed that the udev patch from SJR only apply
the rules upon an unplug/replug of the UPS' USB cord.
you can check the rule application using:
1) lsusb to identify the Bus and Device number (ex: Bus 002, Device 004)
2) then do an "ls -l /dev/bus/usb/XXX/YYY" where XXX is the Bus
number, and
YYY the device number.
you should have "root:nut"--
cheers,
Arnaud
