Hi all,
So i recently got a new laptop for work, namely the HP Elitebook 840 G5, and installed Ubuntu 18.04.
Everything works as expected (or doesn't work as expected, e.g. the fingerprint reader), except for the webcam.
The camera is a Chicony Electronics produced Windows Hello compatible webcam. Now i don't need any of the Windows Hello features, i just need the webcam to work for calls.
I've also tried updating the kernel to the latest stable version, 4.16.13 at the moment, but had no luck with that either.
Here's the output of lsusb :
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 005: ID 04f2:b5e7 Chicony Electronics Co., Ltd

Bus 001 Device 002: ID 03f0:a31d Hewlett-Packard
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
And everything i found in dmesg regarding uvcvideo :

Any idea on how i could get this camera working for calls ?
