<div dir="ltr"><div>Going back to the VID/PID, I was looking up the qmi_wwan.c in the kernel sources and I find that the 1109:9051 is not in the QMI_FIXED_INTF table in the kernel version I am running (3.12.13) !! And in the kernel version 3.12.16 for example, I see the 1109:9051 in the table (correctly as Aircard 340U). But I promise it was just working perfectly fine till the firmware upgrade :) - which means it was either working purely by "chance" (is that possible!!) or that the PID changed after a firmware upgrade (highly unlikely ?). <br>
<br></div>At any rate, I will try out the 3.12.16 kernel tomorrow or just add 1109:9051 to the list in 3.12.13 and see how it goes. Will update tomorrow.<br><br>Rgds,<br>Gopa.<br> <br></div><div class="gmail_extra"><br><br>

<div dir="ltr"><div><div>Hi Aleksander,<br><br></div>Thanks a lot for the suggestions. I tried them out, but that did not solve the problem. I upgraded to libqmi 1.10.2 to get the latest clis .. I cross checked with a couple of other people with Sierra/Netgear 340U modems running linux and they are facing the same issue too. The firmware version just before this latest one was all hunky dory and great, unfortunately the upgrade to the latest has caused this issue.<br>

</div>It was decided not to expose the non-functional ones.<br>
<br>
E.g. the MC7304 (0x1199, 0x68c0) exposed interfaces 8, 10 and 11. 8<br>
and 10 were both QMI (one with raw-ip by default, the other one with<br>
802-3 by default), and 11 was the non-functional one, so it was<br>
removed from the driver.<br>
