Problems solved by technology

However, when the type-c interface is not connected to the device, this periodic square wave output may cause system power consumption of the device where the type-c interface is located; at the same time, when the type-c interface is charged for a long time, it may also There will be interface corrosion, leakage, etc.

Abstract

The present disclosure provides a device detection method, a device detection device, a computer-readable medium and an electronic device, and relates to the technical field of type-c transmission. The method includes: in response to the terminal device charger input detecting the interrupt trigger of the CID, and reading the CID state data; wherein the CID state data includes a first state of the CID before the interrupt trigger and a second state of the CID after the interrupt trigger; When the state is different from the second state, and the second state is the unplugged state, adjust the connection mode of the type-c interface to the uplink port mode. The present disclosure can avoid periodic square waves output between CC interfaces in DPR mode, thereby reducing power consumption and avoiding interface corrosion, leakage and the like.

Description

technical field [0001] The present disclosure relates to the technical field of type-c transmission, and in particular, to a device detection method, a device detection apparatus, a computer-readable medium, and an electronic device. Background technique [0002] Type-c interface is a new transmission interface that has been produced in recent years. The naming primitive is USB (Universal Serial Bus, Universal Serial Bus) Type-C connector, which has the advantages of high transmission efficiency and fast transmission speed. Data, charging, and functions as a video output port. At the same time, because the type-c interface does not need to distinguish between positive and negative like traditional interfaces, it supports positive and negative insertion, so it is widely used. [0003] Since a device connected to a type-c interface involves two roles, that is, a sink device or a source device, the type-c interface needs to be configured in a dual-role port mode (DualRolePort,...
