Abstract:
A computer system is provided. The computer system includes a USB connector, a voltage generator and a detection module coupled between the voltage generator and the USB connector. The USB connector includes a power pin. The voltage generator provides a first voltage to the power pin of the USB connector. The detection module generates a detection signal, and includes an impedance device coupled between the voltage generator and the power pin of the USB connector and a determining unit. The determining unit determines whether a USB device is coupled to the USB connector according to a cross voltage of the impedance device, and provides the detection signal.
