Humm :-/

So flashing the port when MM starts doesn't help to get it disconnected 
it seems. Doesn't the modem get disconnected when the OS performs the 
restart (i.e. when MM gets shutdown)?

Could you post debug logs of MM during the probing phase? I'm assuming 
that the AT+GCAP sent during probing won't even get the reply, so the 
modem won't even be detected after the reboot.

Just wondering, what if the PC gets shutdown? The modem will still be 
connected in that case, and MM won't be able to do anything there. 
Maybe the proper way to handle this is to ensure the external modem gets 
rebooted when the host gets rebooted, and shutdown when the host gets 
shutdown. Is that a possibility you can handle?
