That's an interesting point. The "powerpanel" driver is marked as experimental, but it doesn't bear any relationship to the HID PDC code. Worth a try.

Note that some UPSes don't like switching between USB and serial without power-cycling. If you don't get any results from the serial driver, you may need to completely power down the UPS, and pull it from the wall long enough to let some of the power supply capacitors drain.
