Getting “configured device was not found”, driver/ovrservice/vorpx/computer restarts have no effect. Unity and Unreal Engine demos work, as does Elite: Dangerous. Running Win7 64bit, extended, Rift as main display, aero disabled, antivirus and firewall disabled, VorpX Conf set to DK2. SteamVR throws “HMD not known”, though it manages to light up the camera before timing out.
Anyone else with similar problems?
