Try this my brother:
In order to work it perfectly following packages are required :
These packages can be downloded from debian site.Links are :
Download the latest version available. For me following versions worked :
These packages can be installed by selecting and right click , install with debi installer it will ask you password and done.
Advance users can install from command line.Goto the packages folder and run following commands :
Suppose you have saved on Desktop :
sudo dpkg -i usb-modeswitch-data_20100826-1_all.deb
sudo dpkg -i usb-modeswitch_1.1.4-1_i386.deb
Now we are going to add our modem to List of Huawei,
newer modems in a file. The file name is 12d1:1446 and it is located at /etc/usb_modeswitch.d
Open this file from command line by using following command.
sudo gedit /etc/usb_modeswitch.d/12d1:1446
A text editor will pop-up, where you only need to add 140b in the
TargetProductList= line and save your file. For your reference, the line should be edited as given below.
STEP 3 :
Detach your USB Tata Photon+ EC1261 and insert it again. Most probably your modem should be automatically detected. Right click on Network Manager from the top menu bar, select edit connections,
select Mobile Broadband and click on Add. You shall be able to find your modem.
STEP 4: For the people with extreme bad luck : If still your device is not detected run following command:
sudo usb_modeswitch -c /etc/usb_modeswitch.d/12d1:1446
In my case i have to run this every time i logon to system.
