[linux-uvc-devel] HP Elitebook 840 G5 IR camera not recognized

[Robert S. <san...@gm...>]

Hi,

On the HP Elitebookk 840 G5, the Chicony Electronics produced camera is not
reconized at all by the uvcvideo driver.
I am using Ubuntu 18.04, with the latest stable kernel 4.16.13.

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

And also entries from dmesg regarding uvcvideo :
