Latitude 7440 webcam not recognised

Hello there,

I have a brand new Latitude 7440. I installed Arch Linux on it and the webcam is not recognised. lsusb shows no signs of a webcam, and there is nothing like video0 under /dev.

The webcam is ticked active in the BIOS/UEFI.

External webcams work.

- Has anyone gotten the webcam to work on this or similar models?

- Is there a keyboard switch to turn on/off the camera?
