What to do if USB devices are not responding on ATEN CS1784?

  Jonathan YoungJul 26, 2025
  If your USB devices are not responding with the ATEN Switch, the USB ports might need a reset. Try unplugging the USB cable from the port on the switch's rear panel and plugging it back in. Also, ensure your PC or OS supports USB 2.0, as the CS1784 has a built-in USB 2.0 hub and won't support older systems. If your OS does not support USB 2.0, you can reset keyboard and mouse functions using the [F1] hotkey.

  If Windows isn't recognizing a device connected through the ATEN Switch, it may be a timing issue. Here's how to resolve it: 1. Unplug the KVM cable from the computer's USB port. 2. Go to Windows' System Settings and remove the Unknown Device entry. 3. Plug the KVM cable back in. Windows should now recognize the device.

Why are my mouse and keyboard not responding on my ATEN CS1784?

  If your mouse and keyboard are not responding when connected to the ATEN Switch, it could be due to an improper reset or the KVM switch needing a reset. Try unplugging the cables from the console ports and plugging them back in. If that doesn't work, power off all devices, including the KVM switch, wait five seconds, and then power everything back on.
