To suppress the current consumed by peripherals which consumes during holding an application as much current as consumed during activating the application, host computer controls the consumption current of the peripherals by adding current control data for controlling the current, when the peripherals which are energized by a host computer communicate with the host computer by using packet transmission. Each peripheral further comprises data detection means for detecting current control data among the data received, and variable supply control unit which switches on/off the current supplied for the peripheral.
