Using Multiple USB Devices at the Same Time

If you want to use more than two USB devices at the same time, you can purchase a USB

hub. The USB hub connects to an open USB port on your computer and provides additional

USB ports (usually four or seven). Most USB hubs also have a power adapter and should be

plugged into an outlet.
