Can I Connect USB 3 Cable to USB 2 Port

The Universal Serial Bus, or USB, replaced the ports series and parallel slow found on older computers, as a way of interfacing devices to a computer. The first USB ports were launched in 1996, quickly followed by version 1.1 which has introduced a 12Mbit per second transfer rate. USB v2.0 was introduced in 2000, and offered a 480Mbit per second transfer rate. Most devices require a USB port, so it’s easy to run out of your computer’s free USB ports, but you can add a USB hub for connecting additional devices. Things you need

USB hub instructions
1. Get a hub USB v2.0 from an electronics store or a computer. USB hubs are available in versions not powered or electric, with propulsion devices versions that need to be powered by the USB hub 4 port of Eusbhubs. Unpowered hubs do not work correctly with the devices of low power like mice or keyboards.
2. Plug the power adapter to the USB hub into a wall jack and plug the other end of the power cord of the adapter plug in the socket on the USB hub. This only applies to powered hubs because the unpowered hubs do not use an external power supply.
3. Plug the A-connector on the USB cable into a free USB port of the computer. You can unplug a USB device to do this, then plug in the hub after. The A-connector is the end of the USB cable which is thin and flat.
4. Plug the B-connector at the other end of the USB cable into the port above the hub. The B-connector is square with sides slightly sloped at the top. Depending on the type of concentrator, Windows can notify you the hub was plugged in as a general rule, you don’t need to install the drivers, because they are usually provided with Windows.
5. Connect additional USB devices in downstream on the USB hub ports. Most USB hubs offer an additional four USB connectors, but some centers provide more ports. Windows should automatically detect the USB devices that you plug into the hub, and behaves as if the device is connected directly to the computer.
