I have a Clevo laptop with an integrated Suyin webcam (064e:3410). The webcam is detected, setting it on/off with Fn+F10 works, but there is no image showing up: the screen remains black with cheese, guvcview, v4l2 test utilities, etc.

I have found these two similar posts, among many others after googling many hours, but no solution so far: Integrated webcam detected but not working and Webcam detected but not showing up
Furthermore, the webcam is reported to work with Debian 10, but I have tried it from a fresh and clean live system (USB stick) and I get the same result: https://linux-hardware.org/index.php?id=usb:064e-3410
Any hint will be much appreciated. Thanks.
