Abstract: A USB control apparatus is connected between a power supply and an external interface, and the USB control apparatus includes a first connection port connected to the power supply; a second connection port connected to the external interface; a control unit connected to the first connection port; and a first conversion unit connected between the control unit and the second connection port. The control unit detects a power source outputted from the power supply and outputs first information to the first conversion unit. The first conversion unit detects the type of a connection port of the external interface. The first conversion unit converts the first information into second information corresponding to the connection port of the external interface to the second connection port.

Abstract: A composite product testing system including a main management system, a test equipment and a burn-in apparatus is disclosed. The test equipment and the burn-in apparatus are both arranged in a burn-in chamber of the testing system. First, multiple tested products are respectively inserted in multiple gauges of the burn-in chamber, and a burn-in procedure is activated for providing an aging environment. The main management system controls one of the gauges to connect with the test equipment for the test equipment to perform testing on the tested product upon the connected gauge. After the testing is completed, the main management system then controls the gauge to disconnect from the test equipment and re-connect with the burn-in apparatus, so as to monitor the tested product upon the gauge during the burn-in procedure.
