Webcam reconnu avec hardinfo mais impossible a utilise

Bonjour,

Depuis quelques jour, ma webcam (USB2.0 UVC HD webcam) sur mon PC portable Asus F502C, est reconnu par hardinfo (mais comme keyboard), mais ne fonctionne pas, essai avec cheese, comorama, skype,... et aucun succes.
Voici mon lsusb:

You need to explicitly set elements to the NULL state before

This problem may also be caused by a refcounting bug in the

Re : Webcam reconnu avec hardinfo mais impossible a utilise

Apres un redemarrage de l'ordi, il y a eu un petit mieux, la led de la webcam a clignote, mais plantage de la video juste apres...
Le terminal donne :

Si qq'un a une idee du soucis, je suis preneur.
