An electronic device and its pairing process and pairing monitoring process is provided, which, though relatively simple, can correctly judge if the electronic device connected to a host device and multiple sub-devices is a certified pair so that the replacement by an illegal sub-device can be detected. An electronic device that implements the process according to the command from the host device has a control unit. The control unit controls the electronic device and multiple sub-devices. The sub-devices have reference data memory sections that store reference data specific to the sub-devices. The control unit has a comparing section that refers to the reference data of each of the multiple sub-devices. |
