PROBLEM TO BE SOLVED: To provide an electronic system capable of dynamically switching a communication rate between a plurality of electronic devices connected in series.SOLUTION: A pre-stage communication device 121 and a post-stage communication device 141 are connected to a host controller 101 in series. After a communication rate of the post-stage communication device 141 is controlled to be a predetermined communication rate, the host controller 101 controls a communication rate of the pre-stage communication device 121 to be equal to the same communication rate as the communication rate of the post-stage communication device 141. |
