> Thomas, were you able to test out this branch?

I am sorry - no.

I have two devices, the old one E3276 and the newer one E3372, both branded by 
"Deutsche Telekom". 

I could give the old one a try. But the newer one has still trouble with the 
kernel. (huawei_cdc_ncm).

But before I test mm/nm - I have to look to the kernel,
and I see something, that may motivate me:

Enrico Mioso writes there about success with E3372. (unfortunately he doesn't 
mention the subtype: at-Modem or hilink-router-mode)

I have to confirm this first.
Maybe I can extend his statement for the: E5786 (Telekom Speedbox mini II) - 
it is no at-modem, but the driver also fails.
