How to Use a USB Hub
When computers started coming with USB interfaces, it quickly became easier than ever to connect new peripherals to your computer. Of course, it's not too difficult to use up all of the available USB interfaces on your computer. Fortunately, a device called a USB hub can let you connect even more USB devices to your computer by letting multiple USB devices share a single USB connection on your computer. Connecting a USB hub is surprisingly simple and requires no new configurations on your computer.
