What is a USB hub, its types and features

Today, there are more and more devices that are connected to the computer via USB-ports. It can be mice, keyboards, printers, external hard drives, flash drives, additional cooling fans and other necessary devices. In addition to such necessary equipment, the industry produces even coffee makers and lamps, the power of which is delivered through this port. All this is wonderful, but in the standard configuration computers have only a few USB-inputs. In the presence of a large number of such devices, a problem arises: There is nowhere to turn on the next device. Well, if one of the connected can be disabled without damage to the work. And if there is no such possibility? It is necessary to increase the number of these ports. This can be done if you buy a USB hub. It is a small device that has, as a rule, one input and several USB outputs. The number of such ports on one device can be from 2 to 90, but more often there are models with up to 10 inputs. Design, color and design are very diverse.

USB hubs can be of several types:

  • USB PCI-card, which connects to one of the connectors of the motherboard. To connect, you need to open the system unit and insert this view Concentrator in a special socket. The operation requires, although not very significant, but certain skills and knowledge. If you do not have one, purchase a different type of device. In addition to the installation difficulties, the USB PCI card is not very convenient to use: all inputs are on the back of the system unit, which presents certain difficulties.
  • Passive USB hub. As a rule, such models have from 2 to 6 inputs. Their use is rather limited: they can not provide simultaneous operation of several energy-intensive devices. Concentrators of this type are usually used on laptops.
  • An active USB hub simultaneously connects to the mains and to the computer. It can provide simultaneous connection and operation of a large number of devices (there are models with 90 inputs).

It is very important that when the USB hub is connected, automatic installation of programs and drivers that support the operation of additional ports occurs. After the installation is complete, the system displays a message indicating that it is ready for use.

Sometimes when connecting several USB-devices there are difficulties due to very close ports. There are models in which the inputs are located on flexible wires, for example, CH 170 USB Hub. This device also has a mini USB input, which is also sometimes necessary for connecting cameras, cameras and other equipment.

You purchased a USB hub, connected, but there is a problem: where to put it. There are models that just stand on a desk or a system unit, and there are devices that are designed to mount on a wall or any other vertical or horizontal surface.

In general, there are a lot of models. They differ in the number of ports, the type of their location, appearance, size, method of attachment, installation and, of course, the price. In such a variety, you will undoubtedly find what you want.
