Make sure you’ve connected the camera into USB 2.0 or 3.0 port (not 1.0/1.1). Try to re-plug the camera into different connectors, disconnect all possible USB devices, especially other cameras, USB drives, etc.
Same thing here, head tracking works, but the camera sees unhappy, i’ve installed the driver linked, and it works ok with 0.4 SDK content, but UE4 just doesn’t seem to be happy with it.
here’s the relevant bit from the log file
