I have more to report...

This UPS is waking my test system from sleep mode. The USB connection is 
also broken in the process (the device manager entry is still present 
though), if I restart the driver I just get a "no matching HID device" 
error. I have to re-plug the USB connection to fix.

The log includes me sleeping the system and forcing the UPS on-battery, 
causing the system to wake.

The system will eventually wake w/o the UPS going on battery too.

I've not had this happen with the APC's. I've re-tested a APC ES350 and 
found that it doesn't wake the system nor breaks the driver, however the 
driver does sometimes crash! I've attached a log of that happening, it's 
very easy to reproduce after a couple sleep cycles.

The Eaton is going to power an always-on system, so not a big deal for me.
