As far as I can see, the device is successfully switched to modem mode

Bus 002 Device 004: ID 12d1:1436 Huawei Technologies Co., Ltd. E173 3G Modem (modem-mode)

So the network configuration dialogue should allow using that device. Can you try activating it?

Don't work Manfred.

http://postimg.org/image/uo6iwdekt/2511a9d8/

Try the terminal commands

sudo usb_modeswitch -W -I -v 12d1 -p 15ca -M 55534243123456780000000000000011062000000101000100000000000000

lsusb

and copy/paste all output.

What does "Don't work" mean? Please elaborate what you have tried, and where you are stuck. In case you get an error message, please provide its full text.

I connected the modem, but still the mobile broadband didn't show up to connect.

I even added in network connections the mobile broad band but didn't show in network manager.

It seems to me that the device is already correctly configured, so you should be able to use it with the network configuration dialogue.

With the device plugged in, what is the output of

ls /dev/ttyUSB*

ls /dev/ttyUSB* didn't show anything

but this did

Hi Manfred, Andrew

I have a Teamweaver application which can help you remote login. Is their any such possibility you would like to take to test what's gone wrong if you don't mind

If I re-check some of your output, I see a weird modification of the usb_modeswitch files 40-usb_modeswitch.rules:
...
# Huawei E173u-2, E177
ATTR{idVendor}=="Huawei", ATTR{idProduct}=="1436", RUN+="usb_modeswitch '%b/%k'"
#14ba
...

A vendor attribute of "Huawei" is nonsense. USB vendor IDs have to be four digit hex codes. Have you entered that data? I am inclined to recommend re-installing usb-modeswitch-data to revert the file to its original contents.

No it was there as it is. Even i wonder why it is like Huawei their

Even I changed it now and added hex codes, but still not works

Try

sudo apt-get install --reinstall usb-modeswitch-data usb-modeswitch

unplug the mobile broadband stick
reboot your system

issue the command
dmesg
note down the time code of the last line of the output
plug in the mobile broadband stick and wait half a minute
issue the command
dmesg
again, and copy/paste all lines that have been added since the time code you noted down into this question document.

This question was expired because it remained in the 'Needs information' state without activity for the last 15 days.
