Hi,
The Realtek 0bda:58f4 webcam which XPS 9370 uses doesn't work [1], not sure
if it's because Linux doesn't support UVC1.5:
[ 2.174138] Linux video capture interface: v2.00
[ 2.182580] usbcore: registered new interface driver btusb
[ 2.188376] uvcvideo: Found UVC 1.50 device Integrated_Webcam_HD

[ 2.189001] uvcvideo: UVC non compliance - GET_DEF(PROBE) not supported.
Enabling workaround.

The Realtek webcam (0bda:58f4) has another firmware that supports UVC1.0,
so the current solution is swapping the entire screen for the laptop.
Eventually UVC1.5 will be supported by Linux, so I am wondering if this is
really because UVC1.5?
