Install Huawei E3372h - 320 trouble

Post by spole340 » 10 Oct 2021, 22:20

Hello,
I'm beginner at Linux and I had idea to have mobile internet on server Ubuntu 20.04.2 LTS through Huawei e3372h-320. I have studied that I must switch mode from USB storage to modem, but on the internet is many different topics how can I fix it. I would like to ask you if someone can help me.
I did: lsusb

I tried to do command: usb_modeswitch -v 0x12d1 -p 0x14db -V 0x12d1 -P 0x1506
and it replies:

Look for target devices ...
No devices in target mode or class found
Look for default devices ...
Found devices in default mode (1)
Access device 009 on bus 001
Error opening the device. Abort

when I tried to: sudo usb_modeswitch -v 0x12d1 -p 0x14db -V 0x12d1 -P 0x1506 -J

It replies:
Look for target devices ...
No devices in target mode or class found
Look for default devices ...
Found devices in default mode (1)
Access device 011 on bus 001
Get the current device configuration ...
Current configuration number is 1

with class 2
Error: can't use storage command in MessageContent with interface 0; interface class is 2, expected 8. Abort


I'm not sure that switched number 0x1506 is correct....
then tried to do command mmcli -L but it replied that no modem was found...
but something was done:

usb_modeswitch is included in Ubuntu, it will switch mobile internet devices without user intervention and the USB Id 12d1:14db is an Id after switching, the interface composition after switching only contains a direct net device, there are no serial modem interfaces so ModemManager can't do anything with it.
Net devices like this are handled by NetworkManager and that is where you enable it.
There are no SIM card, APN, or password configurations to be made, your device has read all it needs to know from the SIM card, from linux point of view it behaves exactly the same as a USB Ethernet adapter.

Re: Install Huawei E3372h - 320 trouble

Post by LOM » 12 Oct 2021, 03:16

Your device is a mini router with the mobile connection as WAN side and USB tether on the LAN side so you will get a private IP address from it. (The E8372h is almost the same device except that it also has a WiFi AP on its LAN side that can serve 10 clients.)

There is probably a built-in web server which you can browse at 192.168.8.1, maybe there is an APN setting there or a setting for starting/stopping the mobile link. Everything else looks ok on your tethered LAN side, you've got IP address, gateway, and the interface is up.
