[Nut-upsuser] Nut problems with Centos and Belkin UPS

Hi Arjen

My apologies fro drifting off topic in the other mailing list...:-)

On the bottom of the Belkin UPS unit - is the model number: F6C120auUNV
The "au" is for Australia I think.
"man belkinunv" states that F6C120-UNV is supported - and I assumed that 
the "au" would not prevent this.
I plugged in the USB to gather the information you requested. My 
intention was to use the serial connection and probably still is, though 
if there is a solution via USB - I would certainly consider it.

I tried "lsusb -W" (as suggested) but this seems an invalid option so I 
assume you mean "lsusb -v"
Below is the relevant part of the output from "lsusb -v".

I had a look at the Belkin site recently - and it looks like the model 
after mine comes in a couple of flavours - and they provide different 
software for these two flavours - but my understanding is that my 
(older) model is "single flavour"..:-) I think it is quite possible that 
I have a more basic communication problem with my UPS. I am relatively 
new to Linux - and may well have done something stupid, or not done 
something sensible...:-)

Many thanks for your help Arjen.
