</div>No, that won't make any difference. The device config is presented by<br>
the device firmware. But if you have a Linux PC around, then<br>
replicating the problem on that would be an easy and somewhat useful<br>
test. There *are* issues with the raspberry pi usb host controller<br>
driver. I don't think this should matter (you are obviously talking<br>
just fine to the modem), but it wouldn't hurt to completely eliminate<br>
the possibility.<br>
<br>
Regarding the "missing" second config: All these modern Sierra devices<br>
can be configured for a number of different device layouts, using 1 or 2<br>
configurations. Such changes are non-volatile. I agree that it is<br>
surprising to see such a new device without any MBIM configuration by<br>
default, but this is really the choice of whoever you bought this device<br>
from. Maybe they didn't want Windows8 support?<br>
<br>
Anyway, none of this should conflict with QMI support. And are<br>
definitely talking QMI to the modem. The modem auto-connecting looks<br>
like the most likely explanation so far, and your<br>
"qmi-network /dev/cdc-wdm0 status"<br>
test shows that it is in fact already connected.<br>
<br>
So what we have to figure out is why it doesn't respond to DHCP. It<br>
would have been interesting to see the output of a QMI_WDS "Get Current<br>
Settings" request, but unfortunately that isn't implemented in the<br>
qmicli yet...<br>
