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.
