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 2 values. Give the following command (while the dongle is plugged in):
sudo su
lsusb | grep Huawei
