Now you lost me :(
Should pppd with AT-commands can connect with this modem and firmware or can't it?

If it can't work:
Do I need definitively libqmi or must the gobi-lib work too?

I know the network-manager from my Debian-desktop-PC. But at this embedded system I have no X-server. Is it 
working too? Or do I have to analyze the source to develop my own programm?

Another question: Is it important for dialin-procedure if I have an access-point with LTE or UMTS? Or does it 
no matter? - except speed of course ;)

Speed is the second goal. The first goal is to get it working. At this moment we use the AT91Sam9G20 which 
have just USB 1.1. The plan is to upgrade later to the ~G25 with USB 2.0. Only then a faster solution is 
needed, but then we have more time.
