using nut-ups with apc UPS on USB

[Derek Ragona]

I use nut-ups on a number of systems both attached to a UPS and some as 
network slaves.  In all my systems I use UPS's that have serial interfaces 
and USB, but connect them via serial.

If you read the docs on nut-ups you will see some drivers do support the 
USB's.  You will need to specify the port in ups.conf typically in 
/usr/local/etc/nut
The line would be:
port = /dev/usb0

You can experiment with the port to get the right one.  Nut will tell you 
if is can or cannot talk to the UPS.
