If feasible, you may want to set up the Windows software, and monitor
the communications between the UPS and the software. Check for
SnoopyPro on sourceforge.

I'm going to hazard a guess, from the MxPS (max packet size) field,
that your UPS is using the HID protocol as an easy way to work in
Windows without requiring a special device driver.

actually, newhidups doesn't require a device name (it uses libusb
instead of /dev nodes), so you can put anything in the port field.
newhidups actually detaches the hiddev driver.

Looks like you may need to specify "-x vendorid=0925", and you may
also want to try -DDDDD to see the details of matching.
