@sgunhouse I made disable IR camera drivers from devices settings menu in windows. normal camera driver is active only. I made disable virus protection for camera in settings ESET. and I let to opera for opening only usb2.0 HD IR UVC webcam camera.

I said to windows HELLO, goodby. bUT opera and camera now working.

two cameras working everytime every program. but opera cant understand which camera is IR or normal camera. i set up from settings menu and. result is same. I think opera has camera selection problem on laptop with 2 camera.

asus zenbook has normal camera and IR camera.
The camera normally works when I disable the IR camera. two cameras having problems with each other
