Many hubs can work either as bus-powered orself-powered hubs. After all, USB hub with power supply will enable you to use power flexibly. On the contrary, the self-powered hub ( active hub) is the hub that gets power from the external power supply unit so that it can offer full power (500MA at most).

However, many devices need more power than this hub offers and fail to work in it. The bus-powered hub(passive hub) draws all its power from the host computer’s USB interface, requiring no separate power connection. They are illustrated one by one in below.

Therefore, you should choose a suitable USB hub according to your demand. HUB 3.1 hub supports USB 3.1 anddownwardly compatiblewith USB3.0/2.0/1.1, the theoretical bandwidth can reach up to 10Gbps.HUB 3.0 hub supports USB 3.0 anddownwardly compatiblewith USB3.0/1.1, the theoretical bandwidthcan reachup to 5Gbps.HUB 2.0 hub supports USB 2.0 anddownwardly compatiblewith USB2.0/1.1, the theoretical bandwidth can reachup to 480Mbps.They are USB2.0 HUB, USB3.0 HUB and USB3.1 HUB respectively. USB hub can be divided into three types according to the USB protocol. In addition, it is small and lightweight. With this device, you don’t have to worry about the port is not enough anymore.
