Nut upsuser - Nov 2007 - 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.

Richard.

It probably is. We've seen other combinations here, like 'eu',
'uk' and so
on.

There is and in many cases, it will be better than the serial connection.
Many UPS'es use a fairly verbose protocol, where a faster (USB) interface
helps to prevent timeouts.

No, I wrote 'lsusb -vv' (double 'v'). Apparently, this looks
very similar
in the font you're using... :-)

Good. This device is fully supported through the 'usbhid-ups' driver.
Although the stable nut-2.2.0 version works with this UPS, you may want to
try out the (improved) version from the trunk. If you don't know what the
latter is, just wait for the upcoming stable release, which should be
available shortly (Arnaud?)
