Just about all high-tech and mobile gadgets plug into your computer through a USB port. These In-Desk USB Hubs from Belkin let you quickly plug in cameras and flash drives while saving invaluable computer-desk space. The hubs easily fit into 2- or 3-inch round openings in desks, countertops or conference tables, and connect directly to your computer with the included USB cable.
In the dental treatment room we could use this USB hub to plug in our x-ray sensors and our intraoral cameras. I found this at CableOrganizer.com a great resource for hard to find accessories.
