If you live in a PC/Mac home, IOGear’s Auto Sharing Switch allows two of them to share one USB device or printer. The LED lets you know which computer has the access and by sending a printing task, the switch automatically changes it for you. Because it is bus powered, the GUB211 needs no external power supply. The USB 1.1/2.0 device is compatible with Windows 2000/XP/Vista 32-/64-bit and Mac OS X 10.3.9 or greater and is available for $27.95.
