Abstract
An electronic system, a host device and a control method are provided. The electronic system includes a host device, a cable and a slave device. The slave device receives supply power for operation. The cable is coupled between the host device and the slave device. The host device includes a data transmission interface circuit, a management circuit and a central processing unit. The data transmission interface circuit includes a reset circuit. The reset circuit is utilized for detecting whether the slave device has powered on and accordingly generating a simulated hot plug signal. The management circuit is utilized for determining a hot plug state between the host device and the slave device according to the simulated hot plug signal and accordingly generating a control signal. The central processing unit is utilized for establishing a link between the host device and the slave device according to the control signal.
