Nearly all your mobile gadgets plug in to your computer through USB. The Front-Access In-Desk USB Hub presents four angled ports for the quickest way to plug in cameras and flash drives, while saving your invaluable computer-desk space. The Hub easily fits into a 3-inch-round opening on your desk or other surface, and connects directly to your computer with the included USB cable. * Note: If your desk does not have a pre-drilled hole in it, you can drill one yourself using a 3-inch hole saw (requires separate purchase, not from Belkin).
