       USB Hub refers to a device that can expand one USB interface into multiple ones and enable these interfaces to be used at the same time. USB HUB can be divided into USB2.0 HUB, USB3.0 HUB and USB3.1 HUB according to its USB protocol.
  A usb hub is also called a USB Hub, a device that can expand one USB interface into multiple (usually 4) and enable these interfaces to be used at the same time. Plug one end into the computer case or other devices that are supplying power, and then plug the U disk, USB data cable, etc. into the hub.
  First of all, the term is divided into two parts: USB and hub.
  First, USB is the abbreviation of Universal Serial Bus in English, and "Universal Serial Bus" in Chinese, also known as Universal Serial Interface.
  Second, the Hub is what we often call a hub, which uses a star topology to connect multiple USB interface devices.
