[Nut-upsuser] Can't figure out what is wrong !

[Rémi Lavergne]

Dear nut users,

I have recently installed nut to manage a DELL USB UPS on a DELL server 
running UBUNTU Server.

I have installed nut via apt-get and then configured following several 
tutorials found on the web.

I just try to get a safe shutdown of the server on low battery and if 
possible a clean reboot on power back.

So far I think I don't have communication between the UPS and the server 
but I can't really understand what is happening. Can someone tell me how 
to test my configuration or at least where to start so that I can fix it 
or come back with more precise questions ?

In which files should I look for error messages ?

"dmesg" sais :
usb 2-1.1: usbfs: USBDEVFS_CONTROL failed cmd usbhid-ups rqt 128 rq 6 
len 255 ret -110

Thanks in advance for your help !

Rémi.

P.S : as you can understand I'm not a linux specialist but I really need 
this thing to work so I'll try out any advice you have.
