CIRCUIT, METHOD AND APPARATUS FOR USB INTERFACE SHARING
Document Type and Number:
WIPO Patent Application WO/2016/169140
Kind Code:
A1
Abstract:
A circuit for USB interface sharing, which comprises a primary device module (100), a standby device module (200), a switch module (300) and a universal serial bus (USB) interface (400), wherein a detection end of the primary device module (100) is connected to a signal detection end of the USB interface (400); a first control output end of the primary device module (100) is connected to a first control input end of the switch module (300); a data end of the primary device module (100) is connected to a first data end of the switch module (300); a data end of the standby device module (200) is connected to a second data end of the switch module (300); and a third data end of the switch module (300) is connected to a data end of the USB interface (400). A circuit and apparatus for USB interface sharing and a method for implementing the USB interface sharing enable a USB interface (400) of a terminal to be shared simultaneously as a functional interface of a primary device and a functional interface of a standby device, functions of the primary device and those of the standby device can be completed only by one USB interface on the terminal, and convenience is provided for data transmission between the terminal and an external device.
