raspberry : Pb avec clé USB, 'nl80211' generic netlink not found

[Yann COHEN <yann@ianco.org>]

Bonjour,

Cela fait deux clé que je teste sur la framboise et dans le deux cas
j'ai le même phénomène dans les traces  'nl80211' generic netlink not
found

Cela ne semble pas venir du firmware...

Avec un modprobe cfg80211, le message devient 
wpa_supplicant[3261]: nl80211: Could not configure driver to use managed
mode

Donc pas de connexion, par contre iwlist wlan0 scan fonctionne

Où se trouve donc mon erreur...

Cordialment.

Ci-après des extraits de la configuration du raspbetty pi.
