Two-Port USB 2.0 KVM Switch

The ATEN US221A lets two computers share one USB peripheral such as a printer, scanner or external drive. It draws power from the USB bus so no external adapter is required. Front push-buttons, a software utility or an automatic switching mode select the active host. The unit operates from 0°C to 40°C in non-condensing humidity up to 80%.

Replaces Manual Cable Swapping

Instead of unplugging and reconnecting a device each time you change systems, this switch keeps the peripheral permanently attached and routes the connection electronically. The upgrade is worthwhile when two workstations or a PC and a Mac regularly need the same USB 2.0 accessory without network sharing overhead. Auto Switch mode removes the need for a dedicated print server.

Suits Dual-System Desks Needing One USB Device

Ideal for users who alternate between two computers and want a single USB 2.0 peripheral always ready. Not suited for anyone requiring simultaneous access from both hosts, switching of video or audio signals, or support for USB 3.0 and higher bandwidth devices. Builders needing more than two host ports should consider a larger switch.
