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.

Abstract: A method for establishing a connection between devices having USB Type-C interfaces includes that: a first device determines that a USB cable is connected to a USB Type-C interface; determines a role configuration type supported by a second device; establishes a first USB connection to the second device; displays role information that is of the first device and the second device during establishment of the first USB connection and role configuration types supported by the first device and the second device; receives role configuration information of a user of the first device; and establishes a second USB connection to the second device according to the role configuration information.
