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.

Hi Bjørn,
No these are devices that use the Icera chipset. They have cdc-acm serial
ports and firmware has implemented AT commands for (de)activating the pseudo
Ethernet and getting IP + DNS values etc. Actually applying this patch will
provide little in terms of operation except to make the interface name wwan%d
unstead of usb%d and to flag the interface such that Network Manager does not
try to bring it up via DHCP as soon as it appears, like it would with a fixed
Ethernet interface.
Good tip about the 'unexpected notification 01' I'll look out for that!
Andrew
