ModemManager-1.6.2: does not work with Huawei E3372h ??? -153

Hey,

This is transparent to the user; the user doesn't know whether the
connection will be through PPP or a WWAN network interface. The
PPP-based fields are always there, but they won't apply if the
connection goes through a WWAN network interface. This is not ideal,
but right now there's no way for NM to know the type of interface that
will be used for the connection later on; only when it has been
already established.

That won't interfere no, as long as the network interface renaming
rules are run before MM's own udev rules.

ModemManager doesn't run any usb_modeswitch command itself.
usb_modeswitch is usually run way before the MM rules are applied.

Does the list of ports in the "mmcli -m [N]" output show any "cdc-wdm" port?

Ok, huawei-cdc-ncm is enabled.

But how about the cdc-wdm driver (CONFIG_USB_WDM)?
