When you are purchasing a USB hub, pay attention to both the number of additional USB ports that the hub will provide and whether or not it is a powered hub. You'll know that it's a powered hub if it comes with a power adapter. Devices such as portable music players require a certain amount of power to be provided by the USB hub. Since you're splitting the power from one USB port on your computer across all of the ports on your hub, a powered hub is required to provide certain devices with enough power to communicate with your computer.

It's generally a good idea to choose a port on the back of the computer so the wire isn't visible. It doesn't matter which port you choose. If all of your ports are currently in use, simply pick a device, unplug it from your computer and plug it into the USB hub; it should be back up and running as soon as you plug the USB hub into your computer.
