An ExpressCard device is applied to a computer system, and comprises a USB connector, an ExpressCard interface connector, and a control unit. The USB connector is used to connect with a USB interface provided by the computer system, the ExpressCard interface connector is used to connect with an ExpressCard interface provided by the computer system, and the control unit is used to transmit data to the computer system via either the ExpressCard interface connector or the USB connector at the same time. The ExpressCard interface connector is based on the USB standard so that the ExpressCard interface connector or the USB connector is connected with the control unit via a same USB signal pin. Thereby, the present invention allows a single ExpressCard device without an adapter to be applied to the computer system with different connection interfaces.
