Tobias, to possibly be clearer, a cdc-wdm0 port doesn't always indicate
that QMI is supported.  cdc-wdm0 is a generic port type that can carry
a number of different protocols, of which QMI is only one.  It can also
be used with MBIM and AT commands.  I would try MBIM and if that
doesn't work then you're stuck with AT.
