Hi,

In qmi.sh, add the following line on line 2:

set -x

Then start a second terminal window, and execute:

logread -f

When this is done, bringup the interface:

ifup name



Here is the full log:

In this example it works nicely .. but I see the potential issue in your case.
I'll submit a patch shortly to further improve qmi dial-in.
