Description

Timing USB interface switching equipment

Technical Field

The application relates to a timing USB interface switching device.

Background

With the development of Universal Serial Bus (USB) technology, many electronic devices are provided with USB interfaces, through which communication connections can be conveniently established between various electronic devices for data exchange.

Electronic devices including USB interfaces can be divided into USB Host (referred to as a master Device) and USB Slave (referred to as a Slave Device), where USB Slave may also be referred to as a USB Device. When the USB Host is connected with the USB Device, data transmission can be realized. Under the condition that a plurality of electronic devices are used as USB hosts, how to read data in USB devices through USB interfaces of the plurality of USB hosts is an urgent problem to be solved. For example, the internal management control system of a network security base requires, within 2 different physical networks, the automatic timing information exchange to be implemented with such physical isolation.
