It depends on the UPS model.

OMNIVS1000 units actually need to be polled several times with a short
timeout because of the odd way that their USB-to-serial system works.

Some of the SMARTPRO models seem to work right off the bat, but there
have been reports of timeouts.

Can you post the output of 'upsc' for that UPS? There are some debug
strings in there that will help track this down.

If you are worried about making a mess on install, just build with
'./configure --prefix=$HOME/nut' or something similar.

Also, feel free to post the errors from the RPM build system, and we
can take a look. No promises, because I haven't heard of many people
using opensuse, but it can't hurt to ask on the nut-upsdev list.
