Hello,

today I started more or less successfully the linux-next-kernel from 20120221.

dmesg shows the following:

The change of the Device ID is caused by 
usb_modeswitch -v 12d1 -p 1505  -M "55534243123456780000000000000011062000000100000000000000000000"


But now I am at the end. I can still put in at-command via minicom. But I don't know which.
at+cgact=1 makes the LED blue. ( the color for a umts-connection) 

dhclient wwan0 timed out without results.

ifconfig wwan0 up 

and ifconfig shows that:

wwan0     Link encap:Ethernet  HWaddr 00:A0:C6:00:00:00  
          inet6 addr: fe80::2a0:c6ff:fe00:0/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1

          TX packets:49 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000 
          RX bytes:0 (0.0 b)  TX bytes:15174 (14.8 Kb)


Any hints?

Regards,

Thomas
