PROBLEM TO BE SOLVED: To provide an electronic equipment which can not only recognize the operating condition of a host equipment but also transmit its own operating condition to the host equipment. SOLUTION: A microcomputer IC 16 for controlling can not only control the data supplied from a USB audio IC 13 to an audio signal selector 17 or the like, but also control the data supplied from a USB controller 21 to the USB audio IC 13 via a HUB 14 or the like using the control data transmitted and received via an IC 12 for USB communication or the like. Meanwhile, an audio application 22 can not only control the data supplied from the USB controller 21 to the USB audio IC 13 via the HUB 14 or the like, but also control the data supplied from the USB audio IC 13 to the audio signal selector 17 or the like, using the control data transmitted and received via the IC 12 for USB communication or the like. |
