the good is that it's a HID device, as you've guessed, supported by
usbhid-ups.
though the device has a bad/buggy implementation:
- vendorid/productid,
- and the main "UPS", coded as 00860004 instead of 00840004.
I'll have to create a fix for this one.

the bad news is the I/O errors: until it's fixed, we're stuck!
you should still be able to force compilation/link against the actual
libusb 0.1 (ie not 2.0 compat), and should really do it.
a 2nd thing to check is uhid. iirc, you should either unload it or
blacklist the dev or something like that...

cheers,
Arno
