ATEN US421A - USB Device Switch - 4 x USB 2.0 - Desktop
The ATEN US421A is a 4-port USB 2.0 device switch that allows up to four computers to share a single USB device (such as a printer, scanner, mass storage device, etc.) on a 'one at a time' basis. It features a simple port selection via push buttons, configuration utility, or automatic switching function. The automatic switching function eliminates the need for a print server. A beep tone indicates when one computer switches to another.
