[SOLVED] Interface for tethering with ZTE Open C (Firefox OS)

EDIT: I switched from FFOS 2.1 to 2.0 and everything works.

Hi everybody,

I'm trying to use my phone web connexion on my laptop. Unfortunately, the interface does not appear when I activate the "Modem USB" on my phone :

# ifconfig -a

The dmesg output suggests that it recognize it has a mass storage, even if I only activated the Modem USB on the phone :
