Problems solved by technology

Since in the state of Try.SRC, the first electronic device will try to be the Source, if the battery of the first electronic device has not left the power saving mode at this time, so the power supply has not been restored, it may cause the first electronic device to be in progress. The boot process was terminated and shut down unexpectedly

Abstract

The embodiment of the invention discloses an electronic device supporting Type-C connection. The electronic device comprises a dual-role port, a Type-C interface, a Type-C interface, a Type-C interface, a Type-C interface and a Type-C interface, dRP); and a controller coupled to the dual-role port and configured to detect whether the dual-role port is connected to an opposite terminal device; in response to detecting that the dual-role port is connected with the opposite terminal device, detecting whether the dual-role port is connected with a pull-up resistor on the opposite terminal device; in response to detecting that the dual-role port is connected with a pull-up resistor on the opposite-end device, determining whether the electronic device has power supply capability or not; after the electronic device is confirmed to have the power supply capability, the opposite end device is inquired whether to support the power receiving (Sink) role.

Description

technical field [0001] The present invention relates to an electronic device supporting the USB Type-C specification and a method thereof, in particular to an electronic device supporting a dual role port (DualRolePort; DRP) and a method thereof. Background technique [0002] USB Type-C, also known as USB-C, is a universal serial bus (Universal SerialBus; USB) hardware medium form. The biggest feature in appearance is that its upper and lower ends are exactly the same. Cables, sockets and plugs that comply with the USB Type-C specification are designed to be stronger and easier to use than cables using other USB specifications such as Micro-A, Type-A and Type-B. For example, Type-A plugs can only be inserted into Type-A receptacles in one direction, while Type-C can be inserted into the device regardless of the front and back. This design can avoid the trouble and inconvenience caused by the user inserting the USB device into the connection port by mistake. [0003] Accord...
