If you are trying to communicate with your Power Commander III USB using the supplied 9-volt adapter, but the computer does not see it, this means you have a low battery. A low battery will keep the PCIII USB from communicating. The PCIII USB can quickly drain a new battery (about 20 minutes of use), so make sure to not leave it plugged in longer than necessary. Also, make sure the cable is pushed all the way into the PCIII USB's port. Sometimes the connector needs a fair amount of pressure to fully seat it.
