Just one question, which I should have asked about the DW5821e too: Is
it possible to configure the firmware of these modems to USB2 only, and
do they work with the qmi_wwan driver then?
I suspect that these modems really need the SET_DTR quirk... Or rather
that I should get around to making that default, as it seems most new
stuff needs it and most old stuff doesn't care.
