The UPS wouldn't need to do any USB connections.  It would simply broadcast
the ID and status info via the power line protocol.  An independent 
USB device in the power cable would pick that up and pass on to the computer.
This would work for slaves also.

I could see your point should you want to send commands to the UPS, however.
