je suis sur qu'il s'agit de FN+F9
deja, par ce qu'il s'agit pas du meme modele (MX17 R4 dans mon cas, R3 dans ton lien ... et les poste sont TRES differents)
Puis, par ce qu'au gres des appuis successif sur FN+F9 , j'ai une ligne suyin Corp. qui apparais et qui disparais dans le retour de la commande LSUSB .
j'ai plus le code materiel exact, mais j'avais cherché dans google, et ca correspondais bien a une webcam
