Well, what I need is to correlate the actual battery voltage (as  
measured through a measurement instrument) to what the UPS itself  
reports. A minimum of two measurements is needed, with as much  
difference in battery voltage that is practical between them. Usually,  
a measurement with fully charged and (almost) fully discharged  
batteries will give me what I want. The dirty part here, is that  
you'll need to open the case of your UPS in order to get to the  
battery terminals. You'll also need something to measure voltage with.  
For the latter, a digital voltmeter would be required (a hand held  
multimeter is probably the most practical). Please do note that  
charged lead acid batteries are hazardous. Accidentally shorting out  
the terminals will cause severe personal injury, so if you don't know  
what you're doing, don't make any attempts here.

I was just interested in the VID:PID combination here. Thanks.

First you need to kill any existing instances of the 'usbhid-ups'  
driver. Then fire it up as follows:

     <path/to>/usbhid-ups -DD -a nirvana_ups

This will run in the foreground until you stop it with ctrl-c or after  
sending it a SIGKILL signal. We're interested in the first 30 seconds  
worth of output only, after that it will only repeat.
