Hah, indeed with this I'm able to connect the modem! Thank you very much.

But now, there is another strange problem: The modem only works when  
connected for the first time. If I physically re-plug it, there is no  
/dev/cdc-wdm0 anymore, and obviously ModemManager can't connect.
I assume this is a problem with the kernel modules. I already use the  
latest patches of these modules, but still not everything works as  
expected. Are you also involved into this?
