I've tried for several hours to configure Huawei E173s on Ubuntu 14.04. Only what I get is that Ubuntu sees stick as storage(CD or microUSB) but I'm not able to force it to work as modem(to connect to internet). I've installed drivers which were inside device, also tried with other drivers. Device for sure isn't damaged because on Windows it works. Can you help me find how can I solve this issue?
Some information about device:

lsusb :(it shows modem switched off)

Bus 002 Device 004: ID 12d1:1c05 Huawei Technologies Co., Ltd. E173s 3G broadband stick (modem on)


modem-manager-gui: does not see any device


dmesg(after plug-in device):

  • As I've written my modem is detected as device but it does not want to switch to modem-mode. I've tried everything in this tutorial and this does not help. Maybe some logs can help you detect where is problem? – Furry Nov 28 '15 at 9:14
