IOGEAR's 2-Port USB 2.0 peripheral sharing switch enables two computers to easily share one USB device such as a printer, scanner, hard drive camera, etc. The GUB212 2-Port USB 2.0 peripheral sharing switch features push-button switching so there's no software to install, and works right out of the box. The GUB212 is not OS dependent so it is compatible with any computer running at least a USB 1.1 or higher host controller and an operating system with the corresponding USB 1.1 or higher drivers. *In plain English, you can share nearly any USB device between nearly any two computers without doing anything except plugging it in. We add the caveat "nearly any" due to the fact that despite the backward compatibility of USB 3.0 devices, there are some that just cannot work with USB 2.0 due to bandwidth limitations. That said, you can use most USB 3.0 hard drives and peripherals with the understanding that they will transfer data at USB 2.0 speeds. This means you can use the GUB212 with a USB 1.1 compatible devices and/or USB 1.1 equipped computers, but keep in mind the connection speeds will be limited to USB 1.1.
