Tried to disable webcam according this answer. After all operations webcam is stop working and I have this output (screenshot)

And after rebooting my machine and changing webcam config to default values echo enabled | sudo tee wakeup echo on | sudo tee level

webcam doesn't work. Even after reboot. And another strange thing that after reboot webcam config values always as on the screenshot, despite the fact that I changed them before. Please, help me to figure out what happened
