I use MODEL=upsdrvctl and then set the ups specific stuff in /etc/ups/ups.conf
I have it working on several systems using serial port ups's just fine. 
One of these systems has 4 ups's attached to it. The problem is that they are
attached to the machine via serial ports. I am still fighting the one that is
attached via usb.

See if you can talk directly to the ups. Try "/sbin/newhidups -u root -D -a PS1"
where PS1 is the name of the ups you configured in /etc/ups.conf. It should
return a bunch of stuff about your ups. It took me awhile to get that to work
but I think that is the first step. If the driver cannot talk to the ups then
nut will never work :-)

The above works for me, however I still cannot get nut to start. 
I get the following in the logs:
Sep 25 12:17:45 porky upsdrvctl: Network UPS Tools: New USB/HID UPS driver 0.23 (2.0.2)
Sep 25 12:17:45 porky upsdrvctl:
Sep 25 12:17:45 porky upsdrvctl: Network UPS Tools - UPS driver controller 2.0.2
Sep 25 12:17:45 porky upsdrvctl: No USB/HID UPS found
Sep 25 12:17:45 porky upsdrvctl: Driver failed to start (exit status=1)
Sep 25 12:17:45 porky ups: upsdrvctl startup failed
Sep 25 12:17:45 porky upsd[23661]: Can't connect to UPS [PS1] (newhidups-hiddev0): No such file or directory
Sep 25 12:17:45 porky upsd: Can't connect to UPS [PS1] (newhidups-hiddev0): No such file or directory
Sep 25 12:17:45 porky upsd: Network UPS Tools upsd 2.0.2

At this point I suspect that there is something missing from the driver but
I am not sure. :-(
