I'm not sure there's an easy way to do that; but in this case we may
also be interested in the QMI messages really, because we also want to
make sure the port probing is working as expected; i.e. if this issue
happens not only upon MM start, also when you power cycle the modem,
it could be that the port probing of the QMI port is not completing
successfully, so even if the ports are reported to MM, they're not
used as MM couldn't verify it's a valid QMI port.
