Huawei E3372h-153 USB 4G stick working on Rpi4

Just want to report I have the Huawei E3372h-153 USB 4G stick working
on my RPI4 running Buster without any modifications to the stick.

I bought this stick to have backup for internet as in these times
online seems to be the only way to do anything..

I normally have an older Huawei 3372 model in an old raspi1 used as router.
it needs usb_modeswitch and ppp to connect to the internet.

The new stick E3372h-153 seems to have some Linux build in
and appears when running ifconfig as

enx0c5b8f279a64: flags=4163  mtu 1500
        inet 192.168.8.100  netmask 255.255.255.0  broadcast 192.168.8.255
        inet6 fe80::4b0:4fe1:bfbe:c9c8  prefixlen 64  scopeid 0x20
        ether 0c:5b:8f:27:9a:64  txqueuelen 1000  (Ethernet)
        RX packets 4  bytes 960 (960.0 B)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 28  bytes 4197 (4.0 KiB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

so is assigned IP address 192.168.8.100 here, and at the same time
that IP is added to the routing table
 192.168.8.0     0.0.0.0         255.255.255.0   U     288    0        0
enx0c5b8f279a64


The stick now presents a web interface on 192.168.8.1
So point your browser to 192.168.8.1
there you can specify the PIN code
and start/stop the internet connection, some more options.

It is not so much suited for router, but I could surf the web on my P4 with it.
Also you can add IP addresses to this a bit strange (my LAN is on
192.168.198.XXX) for example
raspi95: ~ # ip addr add 192.168.8.1 dev enx0c5b8f279a64

I did an
ifconfig eth0 down
before testing internet access, dhcpd assigned 192.168.178.95 to that,, not
sure that was needed.
All done on the Pi 4 directly, not via ssh.
Normal SIM card is a KPN internet only 10GB/month.

All this as opposed to wild stories on the web about endless failed attempts
re-flashing being needed for that Huawei model,
So very good, basically plug and play in the Pi4 and a nice web interface.

The BAD part is that the piece of paper that came with the stick mumbles
about auto-updates of the stick's firmware, :-(
Will have to see if I can switch that off,
it also babbles that by using it you agree to auto-updates...
So maybe I should burn it anyways ;-),
but as emergency net access for now it is OK and simple.
Maybe auto-update can be switched off in that browser interface under security,
have not looked yet,
Anyways it works in spite of all the horror stories.
