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