Abstract

The invention discloses a device identification method and apparatus, a storage medium and an electronic device. The method can be applied to the electronic device, the electronic device provides first detection voltage for a preset pin of its Type-C interface, the preset pin is a non-configured channel pin, and when it is detected that a Type-C interface of an external device is accessed to the Type-C interface of the electronic device, the configured channel pin of the Type-C interface of the electronic device has no detection voltage. The method comprises the steps that when an instructionfor indicating identification of the external device is received from a user, the preset pin is grounded; when it is detected that the preset pin is grounded, a trigger signal is generated; accordingto the trigger signal, second detection voltage is provided for the configured channel pin and is greater than the first detection voltage; after the second detection voltage is provided for the configured channel pin, the external device is identified through the configured channel pin. The problem can be effectively solved that the electronic device cannot identify the external device by adopting the device identification method.

Description

technical field

[0001] The present application belongs to the technical field of terminals, and in particular relates to a device identification method, device, storage medium and electronic device. Background technique

[0002] At present, the USB interfaces used on many electronic devices are Type-C interfaces. The highlights of the Type-C interface are slimmer design, faster transmission speed (up to 10Gbps) and more powerful power transmission. Moreover, the Type-C interface supports the "front and back insertion" function that can be inserted from both sides. However, in some cases, the Type-C interface of the external device has been connected to the Type-C interface of the electronic device, but the electronic device cannot identify the external device.
