Hi Giffy and Rachael, here are some trouble shooting steps and things to consider when using the Kinect.
1. Use an integrated USB 3.0 port. The Kinect utilizes a lot of bandwidth; USB extension cables and cheap computer chassis ports may be the cause of both your problems. Plug the Kinect directly into the blue rear motherboard USB 3.0 port, and use as short a cable as possible.
2. Check your power supplies. 3rd party (and manufacturing defected official products) may have faults preventing the Kinect from getting all the power that it needs. You can test if it’s working properly by plugging it into an XBOX ONE USB port, and playing a game or testing capture. Do not use the 1st gen XBOXs Kinect port when testing the power supply.
3. Update your USB drivers. Check your motherboard vendors website for the most up to date drivers. Windows Update may or may not provide a driver with better compatibility.
And bear in mind, you will only see an image in Driver4VR after the service has started.
I hope this helps, if you still have problems please provide details of your hardware and configuration.
