Ao tentar utilizar a c920e me leva ao erro mencionado no Assunto do post.

link do stackexchange: https://unix.stackexchange.com/questions/678358/logitech-c920e-v4l2-ctl-list-devices-cannot-open-dev...

Funciona normalmente no windows. no fedora, manjaro, mint retorna o mesmo erro idependente da maquina, testei em outra tambem linux mint.
