Abstract
A method of switching an apparatus state of a first apparatus having a first universal serial bus (USB) interface connected via a connecting wire with a second USB interface of a second apparatus is provided. The method may include receiving a state switching instruction, setting a level of a configuration channel (CC) in a USB interface circuit corresponding to the first USB interface from a first high level to a first low level via a logic controller of the first apparatus when the state switching instruction instructs the first apparatus to perform a master-to-slave switch, and setting the level of the CC in the USB interface circuit corresponding to the first USB interface from the first low level to the first high level via the logic controller of the first apparatus when the state switching instruction instructs the first apparatus to perform a slave-to-master switch.
