Abstract

Embodiments of the invention disclose an electronic device and an information processing method. The electronic device comprises an embedded control component which comprises a micro control unit, and further comprises a configuration channel logic (CC logic) unit and a communication unit, wherein the micro control unit is electrically connected to the CC logic unit, and the CC logic unit is electrically connected to a first type of universal serial bus (USB) interface arranged in the electronic device; the first type of USB interface supports double-sided insertion of a USB connector of an access device; and the communication unit is used for supporting communications between the first type of USB interface and the CC logic unit and between the CC logic unit and the micro control unit.

Description

technical field [0001] The invention relates to information processing technology, in particular to an electronic device and an information processing method. Background technique [0002] With the continuous development of electronic technology, the Universal Serial Bus (USB, Universal Serial Bus) technology is also continuously developed, and a USB-C type (Type-C) interface appears at present. This Type-C USB interface supports double-sided insertion of the USB interface, which solves the problem that the USB interface can only be inserted in one direction; and the Type-C USB interface has faster transmission speed (up to 10Gbps), greater power transmission ( Up to 100W) and two-way power transmission, based on this, the Type-C USB interface also has various functions, such as data transmission, charging, connecting external display devices as a video output port, and so on. Since different functions require different amounts of power, inside an electronic device (such as...
