What does 'lsusb -vvv' say after the kernel usbhid driver is detached?
(i.e. if you unplug and replug the device, make sure that you re-run
newhidups once before running lsusb).

This makes me wonder if it is just a USB-to-serial bridge. If that
were the case, newhidups would not know how to communicate with it -
the cyberpower serial driver would have to be adapted instead.

What was the compilation error? It needs the types on the right-hand
side, but they may not have been preprocessor defines. (The proper
solution involves some autoconf magic, and I won't have time to fix
this myself - any volunteers?)
