Take a look at the hotplug-ng scripts - they might help. -- - Charles Lepple
Hi all,
I've tried installing NUT from both the Debian packages and the
2.0.4-pre1 source but I'm unable to sort out the USB permissions when
using the newhidups driver and an APC XS series UPS. In each case,
I'm able to run newhidups as user root but running it as user nut
fails:
--- as 'nut'

I've been playing with this for most of the afternoon but I'm out of
ideas. Any and all suggestions are greatly appreciated!
