Hi, we are using the modem-manager and networkmanager from the current git. The last checkout was from May the 9th. It seems that there are communication problems via the AT commands. This is the USB Device we are try to get work with NetworkManager: T: Bus=02 Lev=02 Prnt=02 Port=01 Cnt=01 Dev#= 6 Spd=12 MxCh= 0 D: Ver= 1.10 Cls=ff(vend.)
