Sorry for the the delay, If I remember correctly, that's what happened.

Your UPS doesn't have Usage Page 0x84, 0x85 or 0x86 in its report descriptor - it only has 0xFFA0, which is in the vendor-specific range, and the two Usage fields are just 8-byte unstructured buffers (also with vendor-specific IDs).

It seems that its very poorly and implemented in a very non-standard
way. I mailed the reseller a few days ago, still no answer.

Ok, let me know if you need anything else. I tryed the instructions at
http://www.networkupstools.org/docs/developer-guide.chunked/ar01s04.html
, but it didn't work. As a matter of fact, the generated C files did not
compile, they had garbage in the middle. Hand editing the sources to
make it compile resulted in a non-working driver anyway, probably
because of the not implemented usages.

Happy $HOLYDAY ;)
