USB Type-C Plug and Cable

Abstract

A universal serial bus (USB) Type-C plug and a USB Type-C cable, where the USB Type-C plug includes a dual-role port (DRP) and a role control switch, where the DRP is configured to connect to a USB device, and the role control switch is connected to the DRP and configured to control a port attribute of the DRP, and the port attribute includes a slave device port or Up Facing Port (UFP), a host device port or Down Facing Port (DFP), or no role control. A role control switch controls a port attribute of a DRP such that a USB Type-C cable that includes a USB Type-C plug can control host/slave attributes of devices on both ends of the cable. A user can connect different devices more clearly and explicitly, thereby avoiding a scenario in which a power supply orientation is incorrect.

Dependencies are inferred from the claim text.
