If i send at^ndisdip=1,1,"apn","","",2 through /dev/cdc-wdmX once i will get response and after that running udhcpc on wwanX interface connecting to network.<br>

</div>It is? Haven't heard about that combination before. Do you have a<br>
"lsusb -v" ouput for that device. Huawei are nice enough to use the<br>
subclass and protocol fields to separate different function types. I<br>
wonder what this device says..<br>

<br>
</div>This is getting a bit ugly. But Enrico Mioso has created a NCM driver<br>
similar to qmi_wwan, exposing the embedded management channel as a<br>
/dev/cdc-wdmX device: <a href="http://patchwork.ozlabs.org/patch/269325/" target="_blank">http://patchwork.ozlabs.org/patch/269325/</a><br>
<br>
The driver was made for modems using AT commands on the management<br>
channel, but it should work equally well with QMI. I guess it will be<br>
up to ModemManager to guess the protocol based on either probing or<br>
device ID... The driver won't know.<br>
<br>
But this driver is not yet merged. It is work in progress. You'll need<br>
the two other patches in the series if you want to test it now:<br>
