How to fix E_NUI_INSUFFICIENTBANDWIDTH

While this error can be caused by a software problem (specifically with Windows services) most of the time it's due to a USB conflict or a cheap extension cord.

Kinect Management Service

• Open Windows Search (Press and type in Services and choose the application that appears at the top.)

• Scroll down the services list until you find "Kinect Management"
• Ensure that the service reports "Running" under the "Status" row.
• If it isn't, double-click on the Kinect Management service item to open it's properties window.
• In the "Startup" dropdown, choose the option labelled "Automatic".
• Under the "Service status" group, click the "Start" button.
• Finally, click "OK" then close the Services window.

If the Kinect Management service was already running, this won't help fix your issue. You should move on to other steps.

USB hubs and extensions

If you have your Kinect connected via a USB hub or a USB extension cord, you should try to run it without, even if it means putting it in a non-ideal spot for tracking, as this is only for testing.

Extension cords and hubs can often have low-quality wiring which causes signal degradation and reduces the maximum bandwidth that the cable can support.

USB conflicts
