CyberData, the leader in PoweredUSB technology, offers a set of service/repair devices designed to help diagnose and validate PoweredUSB ports. Each specific test plug has a voltage detector circuitry that detects the proper voltage supplied by the Host PoweredUSB port. If the voltage is within + or - 10% then the light on the test plug will illuminate. Standard USB devices can also be connected to validate the USB communications.
