Um, not sure how to tell which usb device it is...

I've installed NUT and configured it to use HAL to find the UPS. Apparently,
HAL finds it, because (sometimes) the Gnome power manager appears in the
upper panel and reports there's a UPS connected. As far as I can tell, that's
the only "UI" available using NUT in that mode. but I could be wrong. I 
find the NUT docs to be somewhat inconsistent (which is understandable.)

So, my original question is more from curiosity than need.
