Simple, but what a great idea! This 4-port USB hub from USB Geek replaces the plastic grommet that fits in those cord-corralling holes drilled in the tops of computer desks. It’s USB 2.0 and transfers files at speeds up to 480 Mbps. You can connect up to four high-, full-, or low-speed USB devices and still have room to route your cables. It apparently does not have an external power source. The In-Desk 4-Port Hub is $12.00.
