Huawei E3131 and the ignored at^ndisdup command

[Enrico Mioso]

:) Thank you guys for te thrust!
Yes - I'm understanding the general structure of the cdc_ncm driver, in 
preparation to editing it. Yes, I could have made it with libusb, but for the 
moment I was just concentrating on understanding basic USB concepts. I will let 
you know of any step I succeed in taking.
