Problems solved by technology

[0003] However, the inventors have found that at least the following problems exist in the prior art: although the terminal device can supply power to multiple external devices at the same time through the USB interface, it can only transmit data with one of the external devices at the same time. Manually switch the external device to the USB interface capable of data transmission, the switching process is cumbersome

Abstract

The embodiment of the present invention relates to the technical field of communication, and discloses a USB control method, a terminal device, and a computer-readable storage medium. The USB control method is applied to a terminal device. The terminal device includes at least two USB interfaces, a charging switch connected to each USB interface, and a data analog switch connected to the charging switch. The charging switch is used to control the conduction of the charging path of each USB interface. on or off; the data analog switch is used to control the on or off of the data transmission path of each USB interface; the method includes: according to the control of the charging switch on the charging path of each USB interface, a flag information is generated; the flag information is used for Instruct one of the data transmission paths in each USB interface to be turned on; send the flag information to the data simulation switch for the data simulation switch to control the turn-on of one data transmission path in each USB interface according to the value of the flag information. The USB interface that needs data transmission can be switched synchronously according to the specific usage of the user, and the switching process is simple.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a USB control method, terminal equipment, and a computer-readable storage medium. Background technique [0002] USB interface, also known as Universal Serial Bus interface (Universal Serial Bus, referred to as "USB"), is a serial bus standard that connects computer systems and external devices, and is also a technical specification for input and output interfaces. It is widely used in Information and communication products such as personal computers and mobile devices have now expanded to other related fields such as photographic equipment, digital TV (set-top boxes), and game consoles. The USB interface supports functions such as plug-and-play and hot-swapping of devices, and many products have multiple USB interfaces. [0003] However, the inventors have found that at least the following problems exist in the prior art: although the terminal...
