I don't think this is a good idea. A UPS is not a measuring instrument.
The accuracy and resolution that can be achieved is magnitudes away from
what would be needed to *really* make meaningful measurements.
Making this user configurable is not an option, since for most if not all
USB devices, we'll probably remove this once we've ironed out some things
regarding the detection of the devices by the server.
Best regards, Arjen
