Abstract

An embodiment of the invention provides a chip, a concentrator, electronic equipment and a USB signal interruption method and is used for solving the technical problem of lacking a better method for closing USB equipment in the prior art. The chip comprises a USB signal input pin, M USB signal output pins and a controller, wherein the USB signal input pin is used for accessing USB signals, each of the USB signal output pins are used for outputting USB signals and providing the USB signals for USB equipment which is connected with the corresponding USB signal output pin, M is an integer which is larger than or equal to 2, the controller is connected with the USB signal input pin and is respectively connected with each of the M USB signal output pins, and the controller is used for executing a first control instruction to control N USB signal output pins of the M USB signal output pins to stop outputting the USB signals when the first control instruction is received, and N is an integer which is smaller than or equal to M.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a chip, a hub, an electronic device and a method for interrupting a USB signal. Background technique [0002] At present, most electronic devices support USB (Universal Serial Bus, Universal Serial Bus) extended functions, such as AIO (All In One, all-in-one computer), PC (Personal Computer, personal computer), Desktop (desktop computer), notebook computer etc. These electronic devices generally include multiple USB ports (or called USB interfaces), so that some USB devices can be connected externally through the USB ports, for example, a USB mouse, a USB keyboard, a U disk or a USB printer can be connected through the USB ports, etc. , to enhance the extended functionality of electronic equipment. During actual use, it may be necessary to turn off the external USB device. At present, the following two methods are generally used to turn off the USB device. [0003] First wa...
