I'd be very surprised if this doesn't show up as a VISA device. Open Windows Device manager. Look under Ports and see which ones are listed. Then plug in the device (or unplug it) and see if the number of ports change after it refreshes. If it does look at the port that gets added/removed. Assuming one does get added/removed, then this is the COM port to use in VISA calls to talk to the device. How do you talk to the device? You'll have to ask the manufacturer but there is likely a list of serial commands to request data from the device.
In the past I have ran a serial sniffing program that would look at the serial data going to and from the device. I then would run the application by the manufacturer which reads data. I'd then have the serial commands for getting data and I would then re-implement it in LabVIEW, if no documentation could be found.

APC use their own proprietary USB interface. They have two classes, the Smart line which seem to use a USB-HID based interface and the others which have a very primitive USB interface that only about support battery charging, discharging and empty status.

I did not know that. Now that I got back to the office I found the UPS I was talking about was a Tripp Lite. I contacted the manufacturer and eventually they sent a data sheet on how to request UPS status. This was after I reversed the messaging myself, but oh well.
Could you link to the PDF you mentioned? I'm not familiar with the Tripp Lite UPS acting like a HID, as I mentioned before all of mine had a DB-9 for serial communication.
