  The usb hub is also called USB Hub, a device that can expand one USB interface into multiple (usually 4), and can make these interfaces use 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.

  How to use the usb hub
  1. The USB-HUB is a device that provides extended communication. If the Hub is not connected to an external power supply, whether it can drive the 2.5-inch mobile USB HUB hard disk mainly depends on the power supply capacity of the computer expansion port!
  2. Generally, a 2.5-inch mobile hard disk needs to be powered by a computer or a Hub, and a 3.5-inch mobile hard disk needs to be equipped with a dedicated high-power power supply; please do not directly connect to such devices;
  3. In the case of no external power supply: the current provided by a computer USB port is about 500MA, which is barely enough for a 2.5-inch mobile hard disk, and part of it is consumed by the USB-Hub, which is not enough for an ordinary 2.5-inch mobile hard disk.
  4. The front USB ports of many compatible computer cases, due to an additional adapter, coupled with material problems such as wire materials, the power supply capacity is even worse; it is very easy to cause the mobile hard disk to be unusable or even lose data and damage the hard disk;
  5. If your mobile hard disk makes a "click" sound, it is caused by insufficient power supply; for your mobile hard disk, it is recommended to connect the USB-Hub to the integrated USB port on the motherboard on the back of the case to ensure better contact and power supply
  6. Please use the USB power supply cable provided by the original factory when using the mobile hard disk. Ordinary usb cable has thin wire diameter and large loss, which cannot meet the power supply needs!
