Mon PC est un MSI CR72 6M-069XFR acheté en avril 2016.
La webcam n'est pas reconnue ni sous le noyau 4.4.33-1, ni sous le noyau 4.8.9-1.
Si je lance l'outil "cheese", il me dit : "aucun périphérique détecté".
Dans les fichiers journaux, il y a les messages d'erreur suivants (j'imagine qu'il sont en rapport avec le problème, mais étant néophyte, je peux me tromper) :
