That should be the most recent version.

No. It's best to run the driver in debug mode and post the results here,
so that I can have a look what is going on.

	/usr/lib/ups/driver/usbhid-ups -u root -DD -a MGEpc675

We're interested in the first 30 seconds of output from this command,
after that you should Ctrl-C it to stop the driver.

I have NUT running on my openSUSE 10.3 system, so it can be done with
the provided RPMs. Chances are that it is just a permissions problem, so
we should be able to work this out with only configuration changes.

Best regards, Arjen
