Public bug reported:
I installed ubuntu 17.10 on a Dell latitude 5285 detachable laptop.
Unfortunately, the webcams (both rear and front) do not work.
There is no /dev/video* file.
I tried upgrading the kernel to version 4.14 and 4.15rc3, but the problem is
still there.
Below are my lsusb and lspci outputs.
