[Nut-upsuser] Problems suse 9.3, ellipse premium 500

[Peter Selinger]

This is a permissions problem; note the "nobody" in:

> /proc/bus/usb/002:
> dr-xr-xr-x  2 root root  0 Feb  3 12:40 .
> drwxr-xr-x  6 root root  0 Feb  3 12:40 ..

> -rw-r--r--  1 root nobody 52 Feb  3 12:40 002

This should be the ups user. The solution is to set up hotplugging
correctly - something to do with /etc/hotplug/usb/libhidups. There
were some posts on this list by Paul Mogren in January on how to fix
hotplugging in Suse.
