Connect Huawei Modem Linux - USB Modeswitch

Generally, if you plugged a USB modem to a Linux, it identifies the modem, as a USB Storage device. So due to that you can't access internet through your USB Modem. So you must change the device identification. For that, you need usb-modeswitch package. if you currently have internet in your system, you can install it easily.

First you must check whether the usb-modeswitch is already installed in your system. 
For that open Terminal and type sudo usb_modeswitch . If it already installed in your system the output will be like this.


If not you will get this error message 
bash: usb_modeswitch: command not found
Now you can install it by following commands.

sudo apt-get update
sudo apt-get install usb-modeswitch
