First of all, don't confuse concepts. HUB and USB interface are two different things, but USB HUB is inserted on the USB interface.

The computer USB interface 2, USB3.0, represents the USB specification on behalf of the computer motherboard, representing different speeds, and the 3 interface is much faster than the 2 interface. The maximum transmission bandwidth of USB2.0 is 480Mbps (i.e. 60MB/s), while the maximum transmission bandwidth of USB3.0 is as high as 5.0Gbps (500MB/s).

Again HUB, the Chinese name is called the hub, the image point, called the USB expander, can be a USB interface on the computer, extended to a number of USB interfaces, easy to have a number of USB equipment players.

Why use HUB, many computer USB interface is insufficient, or distance is too close, conclusion a device, universal USB equipment will not be able to get in.

What is the difference between the USB interface on the computer and the interface on the HUB divider?

The USB hub is the USB divider, which is to separate a USB interface from a computer to multiple USB ports so that more USB devices can be connected. There is no big difference between them.

USB hub is divided into three types: active, passive and hybrid.

Dynamic: the function of regenerating and amplifying the signal on the connected network medium, the length of the connected medium can reach the maximum effective length, and the power is needed to work. Most of the HUB types are available for this purpose.

Passive: as a connector, it can work without power supply, and it is rare in the market.

Hybrid: it can connect various types of cables, such as shaft and twisted pair.

The current size of the interface on the computer's USB interface and the HUB splitter is different from the signal fidelity. The USB interface on the computer is stable, the signal attenuates little, the interface current on the USB c dock divider will be smaller, and the attenuation of the signal is larger than the USB of the computer. The attenuation of USB signal is larger with the extension of the transmission line.
