For example, the hub control circuit 130 can be a universal sequence hub controller, and the first connection unit 110 and the second connection unit 120, 120A can be corresponding to a universal sequence slot. According to the above configuration, the first electronic device 10 can be coupled to the plurality of electronic devices via the data transmission module 100 for data transmission.

In addition, a first transmission path A and a second transmission path B are disposed between the hub control circuit 130 and the predetermined second connection unit 120A. The data bridge unit is disposed on the first transmission path A for controlling a human-machine interface signal transmission between the first electronic device 10 and the second electronic device 20 when the first transmission path A is turned on.
