The IOGEAR 2-Port USB Cable KVM allows users to share a VGA monitor, a USB mouse, and a USB keyboard between two computers. Users can switch between computers using the wired remote switch button that can be placed on your desk for convenience. It offers an out-of-box solution with no additional cables needed. It supports multiple operating systems including Windows, Sun, and Mac. It is entirely plug-n-play and requires no software to run. It is also powered through the USB bus and thus does not require a power supply to run. It is the ideal KVM for those who want a competitively priced, entry level KVM that will allow them to multitask with two computers at their disposal.
