Hi, <br>
<br>
I have a problem : <br>
<br>
* Debian stretch / kernel 4.9.0.12 <br>
* Sierra Wireless, Incorporated MC7304<br>
* libqmi 1.22.6 <br>
<br>
when launching connections : <br>
<br>

Clearing state at /tmp/qmi-network-state-cdc-wdm1...<br>
<br>
<br>
I deploy libqmi on lot of the same hardware but got problem on the two last installation.
<br>
I think the main events is "Error reading from istream: Error reading from file descriptor: No such device"
<br>
<br>
Do I have the take care of "Warning ** [/dev/cdc-wdm1] requested auto mode but no MBIM QMUX support available".<br>
<br>
what i try so far : <br>
<br>
* use backport kernel : 4.19.0-0.bpo.6-amd64 => same things. <br>
* use libqmi 1.24.6 (download , configure , install ) => same things <br>
<br>
Do you have any idea ? <br>
<br>
if you need more information i can provided it. <br>
<br>
Regards, <br>
<br>
