Now I've got another of those WTF questions. This ups doesn't ID itself 
the same to an lsusb as it does to upsc.
From an lsusb:
Bus 001 Device 004: ID 0764:0501 Cyber Power System, Inc. CP1500 AVR UPS
From a upsc:
device.mfr: CPS
device.model: CP625HGa

????

And while its not your problem, its keyboard and mouse goes away at 
random intervals, and isn't rediscovered by unplugging and replugging 
the hub the dongles are plugged into requireing a powerdown reboot, but 
the reboot isn't needed for an ssh -Y login!  Its the local usb that 
failing? Still scratching head on this, but first move that hubs wall 
wart to the ups. It doesn't need it to run, but...
Cheers, Gene Heskett
