May I know the exact model name? UX5....?
And some model, there are 2 separate camera, one for Windows Hello, and one is for video calls.
I'm not sure if we put camera driver on our website....usually we don't..so which one did you install?
Please kindly go to our C drive, there is an eSupport file, there should be the initial camera driver there.
Or you may uninstall camera driver from device manager, then let it search automatically for the update.
