Method and device for implementing USB endpoint multiplexing

A method and device for implementing USB endpoint multiplexing are disclosed. The USB device of the present disclosure supports at least two USB functional devices, and the number of the USB functional devices that are supported by the USB device is larger than the number of data endpoints of the USB device. The method includes: receiving a request for switching over USB functional devices, where the request carries a function identifier of a USB functional device selected by a user; searching for the USB functional device corresponding to the function identifier according to the function identifier; and switching the USB device to the searched USB functional device. The devices include: a USB device and a host. By multiplexing the USB endpoints, the present disclosure achieves an object of using one USB device as a multi-functional device, and hence saves the cost and enhances the user's experience.
