Huawei E173 driver Linux Ubuntu

This was tested on Ubuntu 14.10. This Ubuntu version has problem with Huawei 3G modem, they cannot be recognized by default. In this test, I use a Huawei E173 USB modem.



There is an option to use app Mobile Partner, and use for connection to the internet, but build in Ubuntu Network Manager works quite nice too. I think fewer apps more system speed.
For the beginning, you have to download a driver. Huawei Driver Linux
Now unarchive to desktop a folder "driver" and open Terminal.
In Terminal write these commands:

•  
• sudo su (write password and press Enter) now go to the folder 
• cd /Desktop/driver
• ./install /root/Desktop

When all done, you can close terminal and start using your Huawei modem.
If still don't work, you may try this:

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

And in text file bottom copy this:
# Huawei E173
ATTR{idVendor}==”12d1″, ATTR{idProduct}==”1446″, RUN+=”usb_modeswitch ‘%b/%k'”

This works on E173 model, if you have different you have to change idVendor un idProduct
and the model id you can check in Terminal with command lsusbwhen a modem is in the USB port.

In this imageidVendorand idProductis 12d1:1436

# Huawei E173
ATTR{idVendor}==”12d1″, ATTR{idProduct}==”1446″, RUN+=”usb_modeswitch ‘%b/%k'”
Save and restart.
