IOGEARs premium USB 2.0 Peripheral Sharing Switch enables four PCs and/ or Macs to share one USB device or group of USB devices through a USB Hub on one-at-a-time base. The peripheral can be assigned to a computer either manually or with hot keys (plug-n-play). Unique advanced management is available through a Windows-based application (included) that can limit or extend the sharing capabilities between one, two, three or four computers.
