Ubuntu – Huawei E3272 Ubuntu


I have a problem with Huawei E3272 modem. Ubuntu 14.04 does not detect it as a mobile broadband modem. If I put my SIM card into my old modem(E3131) everything works, E3272 is just not detected. I have checked lsusb, and here I can see the system detects it as
12d1:14fe Huawei Technologies Co., Ltd.
but I cannot choose it in my Network Connections.

I tried adding usbserial vendor=0x12d1 product=0x14fe in /etc/modules, but it did not change anything. The same goes for adding

# Huawei E3272
ATTR{idVendor}=="12d1", ATTR{idProduct}=="157c", RUN +="usb_modeswitch '%b/%k'"

in /lib/udev/rules.d/40-usb_modeswitch.rules. I also tried installing Modem Manager, but it did not help.

Have you got any idea what could I do, so my system would detect my new modem? I would like to be able to use LTE. 🙂

The same changes is applicable, and needed, in Ubuntu 14.10 as well.

So open the Terminal and copy the following:

sudo gedit /lib/udev/rules.d/40-usb_modeswitch.rules

Add the following lines:

# Huawei E3272 
ATTR{idVendor}=="12d1", ATTR{idProduct}=="157c", RUN +="usb_modeswitch '%b/%k'" 

Save the file, close all open programs and restart the system. Now reinsert your modem. There will be no message or confirmation, but the connection will appear in your panel as it would if you would insert an ethernet cable.
