The important stuff is:

  idVendor           0x12d1 Huawei Technologies Co., Ltd.
  idProduct          0x1446 E1552/E1800 (HSPA modem)

Here are some advices for making our own udev rules.

First step: install usb_modeswitch if it not installed:

sudo apt-get install usb_modeswitch

Second step: run manually the configuration

usb_modeswitch -v 0x12d1 -p 0x1446
