Abstract

The embodiments of the present invention provide a USB connection method and a USB hub, which relate to the field of computer auxiliary equipment, and solve the problem that the existing USB HUB needs to be connected to a USB host device through a specific USB interface. The USB hub includes an MCU, an upstream interface, a USB interface and a first switch module, the USB interface is connected to the first switch module, and the first switch module is connected to the USB interface and the upstream interface respectively, wherein: when the USB device connected to the USB interface is When the USB host device is used, the MCU is used to control the first switch module so that the path between the USB interface and the upstream interface is turned on. The present invention is applied to USB hubs.

Description

technical field [0001] The invention relates to the field of computer auxiliary equipment, in particular to a USB connection method and a USB hub. Background technique [0002] The connection of the data packet signal in the current serial port hub (English full name: Universal Serial Bus-HUB, referred to as USB-HUB) is usually divided into two kinds of uplink connection and downlink connection. Wherein, the uplink is oriented to the host, and when a downlink interface detects a data packet start signal, only an uplink to the uplink interface is established, for example, an insertion operation of a U disk. The downlink connection is oriented to the connected USB device. When the USB HUB detects the data packet start signal on the uplink interface, it establishes a connection to the downlink interface, for example, the computer reads the U disk. [0003] Specifically, refer to figure 1 As can be seen from the internal structure diagram of the existing USB-HUB shown, the exi...
