rated 0 times [ 3] [ 0] / answers: 1 / hits: 10843 / 2 Years ago, tue, november 16, 2021, 8:25:49

I have Ubuntu 14.04 and problem with Mobile Internet (Huawei USB-stick). When stick is plugged in upper left USB slot, everything works fine, when is plugged in any of two slots in lower right - not working at all. At first I thought that device can not be recognized, but Ubuntu recognize it clearly, how do I set modem on?

When in first USB slot:

my.comp@Skynet:~$ lsusb

...

Bus 003 Device 006: ID 12d1:1c08 Huawei Technologies Co., Ltd.

...

When in second USB slot:

my.comp@Skynet:~$ lsusb

...

Bus 003 Device 007: ID 12d1:1c0b Huawei Technologies Co., Ltd. E173s

3G broadband stick (modem off)

...

I hope that this is not duplicate question, I've red (and tried) most of the solutions posted here, none worked

Here's what I did based on this description:

Plug the USB device

Open a terminal, run lsusb:

Bus 001 Device 008: ID 12d1:1c05 Huawei Technologies Co., Ltd. E173s 3G broadband stick (modem off)

Create a file /etc/usb_modeswitch.d/12d1:1c05

Paste this content:

########################################################

# Huawei E173s



DefaultVendor= 0x12d1

DefaultProduct= 0x1c0b



TargetVendor= 0x12d1

TargetProduct= 0x1c05



CheckSuccess=20



MessageEndpoint= 0x0f

MessageContent=

"55534243123456780000000000000011062000000100000000000000000000"

Add corresponding lines to /lib/udev/rules.d/40-usb_modeswitch.rules with sudo gedit /lib/udev/rules.d/40-usb_modeswitch.rules:

# Huawei E173s

ATTRS{idVendor}=="12d1", ATTRS{idProduct}=="1c05", RUN+="/usr/sbin/usb_modeswitch -c /etc/usb_modeswitch.d/12d1:1c05"

gksudo gedit /etc/modules, and add this:

# manual override for Huawei E173s to work

usbserial vendor=0x12d1 product=0x1c05

Unplug and plug the USB device type lsusb. Now it should be
modem on:
```
Bus 001 Device 008: ID 12d1:1c05 Huawei Technologies Co., Ltd. E173s 3G broadband stick (modem on)
```
Now you should be good to go and able to connect via the GUI:

In case it's still not working, refer to the further steps described here: http://metodiew.com/huawei-e173s-and-ubuntu/

Note:

Your device id may vary 0x1c0b or 0x1c05 (or even something else)
