salut la liste,

J'ai un drôle de soucis.
J'ai reçu il y a peu un petit stick USB modem 3G.
C'est un Vodaphone-Huawei K4203.

Les premiers essais n'ont pas été très concluants.
En cherchant un peu, j'ai trouvé cetta page :
http://www.draisberghof.de/usb_modeswitch/bb/viewtopic.php?f=3&t=1970

En deux mots, c'est un dongle certifié W$8 qui fonctionne avec le prot=
ocole MBIM sans devoir être "modeswitché". Et il possède un =
mode compatible W$7 qui le fait apparaître comme un périphér=
ique cdc_ether. Il suffit de le "modeswitcher" en lui envoyant le message s=
pécifié.

J'ai donc essayé de le switcher après l'avoir branché sur mo=
n desktop et cela fonctionne bien. L'envoi du message le fait basculer en c=
dc_ether et il apparaît dans les périph' réseau (voir <lsusb=
> avant [1] et après [2] <usb_modeswitch>).

La même manip' sur mon laptop ne donne absolument rien. Du tout. Impos=
sible de le switcher.

Mes deux ordis sont pourtant tous les deux en Strecht/Sid, la version de /u=
sr/sbin/usb_modeswitch est la même et les infos retournées par <l=
susb> sont identiques avant de le switcher.

Une idée d'où commencer les recherches ?

Un autre truc aussi qui me chiffonne concerne MBIM. Les messages de /var/lo=
g/message indiquent ceci lors de l'insertion du dongle dans le port USB (vo=
ir aussi [0]) :
kernel: [24889.936114] cdc_mbim 1-2:2.0: bind() failure

Donc, il y a apparemment aussi un soucis lorsque le système essaie le =
protocole MBIM.

Merci d'avance pour votre aide.
