The ATEN US221A is a USB 2.0 peripheral switch that lets two Windows or Mac computers share one USB device, making it suitable for home offices and desks where a printer or other peripheral needs to serve two computers.
Recommended For
- Home-office users with two computers and one USB printer who want to share the printer without moving its cable; the switch can also automatically transfer printer access.
- People who alternate between two computers and need to share one USB scanner or other single USB peripheral, switching control between computers as needed.
- Users who want to share a USB keyboard between two computers while keeping their monitors separate; a customer report describes using the switch this way.
- Windows and Mac users who are comfortable selecting which computer gets the peripheral using the switch’s physical button; ATEN lists both platforms as compatible.
