Are you sure none of these export QMI via the CDC Ether control
interface?  Or are they not Qualcomm devices at all?

As usual, if you see a spurious "CDC: unexpected notification 01" logged
from cdc_ether, then there is reason to examine those closer.  If you
don't see any such messages, then there isn't any QMI there.
