Problemas com uma câmera web Genius VideoCAM Look.
Colegas, comprei recentemente uma câmera web Genius VideoCAM Look mas
estou tendo problemas para fazê-la funcionar corretamente. Compilei o
kernel com suporte ao módulo sn9c102 e quando ele é carregado a luzinha
verde que está encima da câmera acende e aparece o seguinto nos logs:
