One PC has a USB-A port, the other runs USB-C, and your peripherals keep getting swapped by hand. This ATEN switch handles both host types natively – one Type-A, one Type-C – so you're not hunting for adapters. Four device ports sit on the switch side. Hit the button or grab the included remote port selector from your chair, and everything flips to the other machine. USB 3.2 Gen 1 keeps you at 5 Gbps. Hot-plug devices in or out without a reboot. No drivers, no software. Windows, macOS, Linux. Compact enough to live under your desk
