An electronic device including a housing, a connector port and a switching device is provided. The connector port is embedded in the housing for a peripheral device inserted therein to electrically connect thereto. The processor is electrically connected to the connector port and comprises a detection pin and a 1-wire pin. The switching device is coupled between the connector port and the processor to selectively connect the connector port to one of the detection pin or the 1-wire pin.
