Maybe we can look at the native OS X HID API. (That was one of the
goals of libhid, but it turns out we can cover most of the other
Unix-ish systems all by using libusb.)

What I was thinking was to have a new NUT driver that is really a
metadriver - it would talk to OS X's power management drivers,
allowing you to run NUT on that computer in cases where newhidups
won't work, or is messy to install. Then, any other equipment plugged
into that UPS could connect to the master.

The easiest thing might be to post the complete upsc output.
