Hi…I can perceive what’s going on however I don’t have a clue why or how to fix it. Alter : I do know why and how.
There is a contrast between the drivers connecting to a gadget and the switch distinguishing and managing the gadget.
In your logs the Sierra has drivers append to it 20 secs before the Telit has its drivers join. I accept this is a result of the postponement on PCie0 power up versus the USB power up.
In any case, the Telit is recognized by the switch 10 seconds before the Sierra.
