Hmm, I misread that. I assumed it was just a pair of 8-byte buffers (the way most of the HID USB-to-serial converters are laid out), but "Size: 8" is in bits.

The interesting part is that "008c..." is the HID Usage Page for bar code scanners.

You can try running usbhid-ups in "explore" mode, as explained here:

   http://www.networkupstools.org/docs/developer-guide.chunked/ar01s04.html#hid-subdrivers

The driver keeps looping and reading the values, and you can see whether they correspond to various power states (on battery vs on AC, low battery, etc.)
