Ok let’s face it: the Linx windows 10 upgrade is breaking the camera drivers, both front and back.
It appears there is an updated driver from Intel that get installed and the camera are not working anymore.
The fix is to force install a specific driver. Open windows device manager and expand the system devices tree to locate two devices named « camera sensor ov2580 »
Force install this driver for EACH device (so twice) :ov2680_ov5648
Please use the driver Info file called 2680.
The device will first show up in warning state. Reboot. Test camera, that should work.
Good luck !
