v4l2-ctl --list-devices
Cannot open device /dev/video0, exiting.
 
It looks like that I cannot turn the camera on (it is an internal camera).
fn+f6 does not do any thing.
The worst is that this camera has been workig in the past!

Here is a traditional favorite for enumerating Video devices:
 
[jwesterd@jwesterd-f33 Citrix]$ v4l2-ctl --list-devices
Live! Cam Sync 1080p: Live! Cam (usb-0000:00:14.0-2.4):
/dev/video2
/dev/video3

Integrated Camera: Integrated C (usb-0000:00:14.0-8):
/dev/video0
/dev/video1
 
[jwesterd@jwesterd-f33]$ rpm -qf /usr/bin/v4l2-ctl
v4l-utils-1.20.0-1.fc33.x86_64

I don't see a camera in lsusb.

So bad usb cable, bad usb socket, bad usb camera, or kernel issue
causing the driver to not allocate memory (or some other resource) and
finish loading.
