The US224 is a 2-port USB peripheral sharing device that enables 2 computers to share the use of 4 USB devices - a keyboard, mouse and up to two peripheral devices. It eliminates the added expense of having a separate USB keyboard, mouse and peripheral device for each computer. The US224 all-in-one design allows for a neat and tidy installation - no need to connect 2 separate USB cables to the computer, thus eliminating cable clutter.
