which USB device is this (that's waking up my Mac)

My Mac Pro keeps waking itself up when I put it to sleep and go to work. Here's what I see in the console log:

So, Port 2 of Hub at 0x5d000000, but according to About My Mac, none of the USB devices have this address. Here's the relevant part. What am I missing - which device is waking it up and how do I stop it??
