In response to the advent of USB 2.0 and the greater speed of connection for the many peripherals, ATEN has developed the US-221 (2 port) USB 2.0 Peripheral Switch. This peripheral sharing device enable 2 PCs to share a single USB peripheral on a one-at-a-time basis using a simple hotkey, the front panel pushbutton, or Windows AP control software to transfer peripheral control among actively connected PCs. This is a perfect tool for today's SOHO environment.
