Estoy extraño. Tengo un portátil Acer Aspire serie 5515 que tiene una cámara web incorporada. Cuando abro Cheese, dice: "no se encontró ningún dispositivo". Camorama dice: "No se pudo conectar al dispositivo de video. Verifique la conexión".
Ni lspci
tampoco lsusb
contiene ningún registro que pueda ser una cámara web. Es casi como si no hubiera cámara web en el sistema.

Ayuda.
PD: Bueno, estoy empezando a pensar que la cámara web simplemente está físicamente rota. No veo otra explicación para que no aparezca lsusb
