Hello,

I've got a T400s (2808-D5G) running smoothly under Debian Wheezy/ testing.=
=20
My only issue is the WWAN module, which I'm unable to get working, neither =
at=20
the commandline with wvdial nor gui with vodafone-mobile-connect.
Maybe someone here can give me a hint how to get things working?
Sorry for posting that much information.


uname -r: 3.2.0-2-amd64

The necessary kernel modules are loaded:
lsmod|grep cdc

er,btusb

dmesg tells me, the modem is known to the system:
dmesg|grep tty
[473231.125739] cdc_acm 2-4:1.1: ttyACM0: USB ACM device

[473231.127770] cdc_acm 2-4:1.9: ttyACM2: USB ACM device

I tried several sim-cards (o2, e-plus, vodafone) and adjusted the=20
/etc/wvdial.conf.
But whether I inserted a sim-card or not, the modem answers each and every=
=20
time, and I want to emphasize: even without any sim-card inserted, e.g.;
wvdial o2

=2D-> Try again and look into /var/log/messages and the wvdial and pppd man=

pages for more information.

After that wvdial tries on and on to get a connection.
Does anybody have a hint for me, how to get this modem working?

greetings
