2 x 1 USB Peripheral Switch gives multiple computers access to a single device, such as a printer, camera, scanner or external storage device. Active-port LED indicators clearly identify which computer is being used. Switch works with USB 1.1 and 2.0 devices at transfer speeds of up to 12Mbps and connects a USB device at up to 30' from your computers. Easy-to-use switching software gives you immediate access to your USB device. Once connected, your device stays available to all connected computers, eliminating the need for you to unplug and reconnect it to another computer. Switch requires no power supply. Switch is compatible with Windows 98, 98SE, ME, 2000, XP and Mac Os X. Switch is not compatible with Mac OS X v10.3.x and does not support multifunction printers.
