# Configuration
By default, your linux box would register your Huawei E8372 as a Mass Storage device and not (somehow) as a modem. First, make **sure** you have the exace same device we're talking about. This can be confirmed by looking at two values using the following command (while the dongle is plugged in):
As an elevated user:
~~~~
    # lsusb | grep Huawei
~~~~
- Now look exactly for `12d1:1f01` - not overlooking a single character mismatch. If all good, proceed.

- Using your favourite editor, with elevated privileges, create a new file called **70-huawei_e8372.rules** in **/etc/udev/rules.d/**

    `# gedit /etc/udev/rules.d/70-huawei_e8372.rules`

- Paste the following piece of code in it, and save it:

    `ACTION=="add", SUBSYSTEM=="usb", ATTRS{idVendor}=="12d1", ATTRS{idProduct}=="1f01", RUN+="/usr/sbin/usb_modeswitch -v 12d1 -p 1f01 -M '55534243123456780000000000000a11062000000000000100000000000000'"
ACTION=="add", SUBSYSTEM=="usb", ATTRS{idVendor}=="12d1", ATTRS{idProduct}=="1f01", RUN+="/bin/bash -c 'modprobe option && echo 12d1 14db > /sys/bus/usb-serial/drivers/option1/new_id'"`

- Finally, reload all the udev rules by:

    `# udevadm control --reload-rules`
    
- Now restart your PC and you're good to go now. Whenever you plug-in your dongle, you'll have it automatically registered as a modem.
