This error usually has two possible causes.
- A bug occured during the Kinect for Windows driver installation, leaving one or more devices as “unknowns” until manually refreshed.
- The adapter is not sending 12 volts power to the Kinect, either because it’s not plugged into a working power outlet, or because it’s faulty.
When using Amethyst Installer
If you used Amethyst Installer, it already attempted to fix this.
Open Device Manager, you can do so by right-clicking on the Start Menu button. In Device Manager, locate the Other Devices category and extend it. In there you should see up to 3 of the following devices:
- Kinect for Windows Security
- Xbox NUI Camera
For each of them, right-click, then Uninstall device then OK.
Don't uninstall anything else!
The Other Devices category may contain devices unrelated to Kinect. Only uninstall devices matching the list above!
First, check that your adapter is getting power. There should be a light either where the Kinect plugs in, or on the part that plugs into the wall. If you don’t see any light. Try connecting it to a different outlet, but you probably have a faulty/broken adapter.
If you just purchased the adapter, try returning it or asking for a refund if possible. Then get another adapter from a recommended source.
