Bonjour.
Grâce à "la brocante de mamie" j'ai acquis un vieux phone Samsung
GT-B2710, excellent, modem etc.
Wammu me permet d'accéder aux fonctionnalités (envoie de SMS ...)
ce qui montre que le système reconnaît le SIM identifier sous le mode
modem.
Lorsque je le branche en USB en mode "mass-storage" il apparaît bien
sous ce mode :

D'abord, le système le voit comme un modem :)
Puis se ravise et le voit comme usb-storage et lui donne l'ID device
/dev/sdc.
Apparemment le système ne reconnaît pas le système de fichier (VFAT).
Comment lire et écrire sur ce média ?
Merci
