Problemas com a webcam no Centos 6.6

1

Não consegui algumas webcams diferentes trabalhando no CentOS 6.6. (Logitech C270 & Creative Live! Cam Sync HD)

Acho que está relacionado com o udev, mas inseguro. Os itens a seguir são meus /var/log/Xorg.0.log e /var/log/messages . Acha que é um teclado?

De acordo com o relatório de bug do CentOS 7815 referenciado por mogga, o bug já foi corrigido em kernels posteriores (a partir de 2.6.32-504.1.3.el6). Se você não tiver feito isso, você deve atualizar o kernel para o kernel mais recente do CentOS-6. Isso deve resolver o problema.
