The printer says 'offline.' The scanner's not showing up. Someone on the other PC switched it. You've been here before.
The US221A lets two computers share one USB peripheral—printer, scanner, external drive—without the daily tug-of-war. Flip the pushbutton, or let Auto Switch detect which PC actually needs it. Or load ATEN's configuration utility and set it to hand over automatically.
Works with Windows and macOS. Handles multifunction printers without drama. One-at-a-time sharing means no corrupt files, no half-printed pages, no 'can you check if it's connected' Slack messages at 4:52 on a Friday.
Small device. Big time-saver for any shared workspace
