Where did I mention USB? I also am giving up on the original question because it was answered. The question I posted above about the Roomba to Bluetooth adapter, I want to know if I could buy/build one of the adapters and plug it into one of my PowerBooks (The cable that connects to the Roomba is a Mini-Din 8 cable) then connect to it with a PC that has a Bluetooth adapter. It should work, the interface is just serial.
