Hi Lars,


Just following up on this. I've not been able to track down one of the
actual modems and have had radio silence from my colleagues who did the
original work.

Is the 1/2 patch of this series acceptable on it's own? (should I rebase
and resubmit it).



Patch 1/2 for NetIndex UX302NC USB modem has the same error as patch 2/2 for the Docomo USB modem, both are LTE CAT3 devices and there is no mfgr providing only a serial ppp dial-up modem interface for high-speed devices like these, they always have a direct net interface.

I have dug up the driver installer from NetIndex web site, the interface usage is:

MI_00 NCXX UX302NC HS-USB Diagnostics
MI_01 NCXX UX302NC HS-USB Modem
MI_02 NCXX UX302NC HS-USB Application
MI_03 NCXX UX302NC Ethernet Adapter


and info in the driver files tells us that the chip mfgr is Qualcomm and the net interface is QMI so it must be blacklisted in the option driver.


thanks
Lars
