That's what I did first, but it does not tell that much, just an additional 

  rndis_host 1-3.1:1.10: ACM capabilities 0f, not really RNDIS?

and when I remove the goto, it continues with

  rndis_host 1-3.1:1.10: RNDIS init failed, -32



I have added an additional command at the beginning of the while loop, printing the 
type, subtype and length field, so the full output is:

rndis_host 1-3.1:1.10: HDX: Entry Type 0x24  SubType 0x00  Len 5
rndis_host 1-3.1:1.10: HDX: Entry Type 0x24  SubType 0x02  Len 4
rndis_host 1-3.1:1.10: ACM capabilities 0f, not really RNDIS?
rndis_host 1-3.1:1.10: HDX: Entry Type 0x24  SubType 0x06  Len 5
rndis_host 1-3.1:1.10: RNDIS init failed, -32




The problem seems to be that the linux kernel expects strictly differences between 
ACM and RNDIS devices, while Nokia seems to have mixed them into one.

Yup, I get /dev/ttyACM0, where I get answers to AT commands and even ppp frames:

OK
AT+CGDCONT=1,"IP","internet.eplus.de"
OK
AT+CGDATA="PPP",1
CONNECT
...pppframes...
