Senhor @egydiocoelho não há item desabilitado. Listei todos os itens: funcionando corretamente. Testei também a solução posta pelo senhor @MaClane. Não surtiu efeito. 

Não é problema do SO, pois a cam também não funciona no GNU Linux. Deve ser problema na própria webcam ou no flat cable ou problema da nova versão da BIOS .16 do modelo.

Não há como testar, pois o flat é difícil de conseguir aqui no Brasil e uma webcam nova também. 

Já tirei a moldura e tirei e reconectei o flat da webcam, mas não surtiu efeito. Só o microfone da webcam funciona corretamente.

Ok! O que acontece quando você reinstala o windows, pressionando alt+f10?

Eu formatei o pc duas vezes para instalar e reinstalar o windows 10 build 2004. Sem sinal de vida da webcam. Ela não é detectada.

Agora instalei o manjaro 20 e a webcam não é detectada nos componentes do sistemas, após a listagem.

Com desmeg o hardware é listado?

A listagem completa no arquivo txt.

Então @MaClane, não consegui identificar a webcam, após listagem dmesg.

MaClane

Para que essa webcam funcione é necessário instalar os módulos "gspca". No terminal, como root, digite:

# apt-get install gspca-source

Feito isso devemos adicionar uma linha no arquivo /etc/modprobe.d/blacklist para impedir o módulo que já vem instalado no Ubuntu 8.04 ou 8.10 de carregar. Edite-o com o comando:

# gedit /etc/modprobe.d/blacklist

Não uso nenhuma uma versão baseada no GNU Linux.
Uso o Manjaro, baseado no GNU Arch Linux.

Vou tentar a sua solução e posto retorno.
