I have a TATA Photon+ (Huawei EC1260) mobile broadband device and am unable to establish a connection either using wvdial or the network manager.

Here is my wvdial.conf

[Dialer Defaults]
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
stupid Mode = 1
Modem Type = Analog Modem
ISDN = 0
Phone = #777
Modem = /dev/ttyUSB0
Username = internet
Password = internet
Baud = 9600

and here some info from /var/log/messages

Is this a network problem or device problem?
