Abstract

The invention provides a method for identifying an accessed USB Type C device by an electronic device. The method comprises the following steps of receiving a prompt signal of connection state change,wherein the prompt signal at least comprises an access signal of the USB Type C equipment; when the prompt signal is an access signal, closing a USB port associated with a preset first characteristicsignal, wherein the USB port comprises a first port and a second port of an electronic equipment processor, the first port is connected with a first pin of an electronic equipment USB Type C interface, and the second port is connected with a second pin of the electronic equipment USB Type C interface. According to the application, a hardware chip does not need to be added, and the hardware cost is reduced, at the same time, the port in the CPU is directly connected with the USB Type C interface, so that the signal effect is better, and the application risk caused by using a third-party product is also reduced.

Description

technical field [0001] The present application relates to the field of computers, and in particular to a method for an electronic device to identify an inserted USB Type C device. Background technique [0002] Currently, laptops support the USB Type C interface. The USB Type C interface can not only support USB data transmission and charging functions, but also support video transmission functions (DP Altmode). However, most of the low-end notebook computers only support the data transmission and charging functions of the USB in consideration of cost, and do not support the video transmission function. Therefore, when such a USB Type C interface is connected to a notebook computer, the operating system of the notebook computer prompts an error message that the device cannot be recognized. [0003] Currently, there are mainly two methods to solve the above problems: [0004] One method is to establish a connection from the USB interface pins of the South Bridge of the note...
