I have a problem with Huawei E3372 modem.

Xubuntu 18.04.2 LTS did not detect it as a mobile broadband modem. E3372 is not detected.

I have checked lsusb, and here I can see the system detects it as 12d1:1506 Huawei Technologies Co., Ltd. but I cannot choose it in my Network Connections. It displays Mobile Broadband not enabled.

I have added

Huawei E3372

ATTR{idVendor}=="12d1", ATTR{idProduct}=="1506", RUN +="usb_modeswitch '%b/%k'"

in /lib/udev/rules.d/40-usb_modeswitch.rules.

I followed the steps in the posts

Huawei E3272 Ubuntu and Huawei usb 4G modem not detected

but in vain

configPack.tar.gz does not contain 12d1:1506. hence the following command 

tar xf /usr/share/usb_modeswitch/configPack.tar.gz 12d1\:1506

didn't worked. Hence I followed the same code in the post

tar xf /usr/share/usb_modeswitch/configPack.tar.gz 12d1\:14fe

and went to the folder /usr/share/usb_modeswitch/

cp 12d1:14fe 12d1:1506

and added the line in the following file

add line to file /lib/udev/rules.d/40-usb_modeswitch.rules:

ATTR{idVendor}=="12d1", ATTR{idProduct}=="1506", RUN+="usb_modeswitch '/%k'"

Still it didn't work.

Again tried, added the following to the file /lib/udev/rules.d/77-mm-usb-device-blacklist.rules:

ATTRS{idVendor}=="12d1", ATTRS{idProduct}=="14fe", ENV{ID_MM_DEVICE_IGNORE}="1"

Nothing worked so far.

Your help is much appreciated. Thanks in advance.

Here is a simple solution, that works for both 16.04 and 18.04.

None of the above steps are necessary.

I have just purchased a Huawei E3372H, so I can save you 2 hours of time wasted on scouring your system and writing new udev rules and usb_modeswitch configurations (which is what I did, LOL).

The E3372 does not show up as a mobile broadband device. It shows up as an ethernet device in the Network Connections Manager: e.g. 'Ethernet Network (HUAWEI MOBILE)'.

Users may want to disable the 'Autoconnect' option in the 'General' tab of the connections editor, otherwise a connection will be automatically made upon boot-up/log-in.

Note, when disconneted in the network manager, the dongle light will still appear to be connected. This can be positively switched off by going to the router url (find it in network manager, Connection Information, Default Route (e.g. 192.168.1.1)) in your web-browser, and clicking on 'Disable Mobile Data'.
