Circuit, Method and Apparatus for USB Interface Sharing

Abstract

A circuit for USB interface sharing includes a host device module (100), a slave device module (200), a switch module (300) and a Universal Serial Bus (USB) interface (400). A detection end of the host device module (100) is connected to a signal detection end of the USB interface (400). A first control output end of the host device module (100) is connected to a first control input end of the switch module (300). A data end of the host device module (100) is connected to a first data end of the switch module (300). A data end of the slave device module (200) is connected to a second data end of the switch module (300). A third data end of the switch module (300) is connected to a data end of the USB interface (400). A circuit and an apparatus for USB interface sharing and a method for implementing the USB interface sharing may enable the USB interface (400) of a terminal to be shared simultaneously as a functional interface of a host device and a functional interface of a slave device, such that functions of the host device and functions of the slave device may be completed by one USB interface on the terminal, and convenience may be provided for data transmission between the terminal and a peripheral device.
