Following the guide for setting up RNDIS-based dongles:-
https://wiki.openwrt.org/doc/recipes/ethernetoverusb_rndis
I do not get the dmesg output suggested, instead I get:-

lsusb identifies my USB stick (Huawei E3372h) correctly as
so it looks like usb_modeswitch has worked correctly.
Any ideas on what has been overlooked?

It looks like an "eth1" device was created for the modem instead of the usual "usb0". Either way you would next attach a network to that device as a DHCP client and you should obtain an IP address from the modem.
usb_modeswitch is generally not required on newer devices. If they have a storage mode it can operate as both modem and storage at the same time.
Many thanks for the reply. The eth1 interface works like you said.
Not sure I understand about whether usb_modeswitch is required. Maybe the guide I mentioned needs updating...
I have 4G Modem E3372, I install kmod-huawei-cdc-ncm, etc... but Why I can use the modem?
the logread | grep cdc, it's just like this

The other guy is using cdc-ether.
Hot plug the device and look at the last lines of the log (unfiltered). Should start with "New high speed USB device" then show the drivers activating.
This is the important line, an interface being started with the modem's MAC address
cdc_ether 1-3:1.0 eth1: register 'cdc_ether' at usb-0000:00:1a.7-3, CDC Ethernet Device, 0c:5b:8f:XX:XX:XX
I have to install the two or just one? just huawei-cdc or just cdc-ether?
ok @mk24 , I already have it,
here the logread for hotplug it :
