tata photon not detecting in ubuntu

-
Problem: I am connecting my tata photon usb modem with ubuntu 13.04 but it is not detecting.

Answer:- check whether usb_modswitch package installed

$ dpkg -l | grep usb-modeswitch
if it installed let we know your hardware vender id and product id.
Plugin your device, open terminal and execute lsusb

Identify the device, an example line could be

Bus 001 Device 003: ID 12d1:1d35 Huawei Technologies Co., Ltd.

Carefully take a note of numbers like ****:YYYY. The **** defines vendor Id and YYYY defines product id. In above example vendor ID is 12d1 & product ID is 1d35

Execute sudo modprobe usbserial vendor=0x**** product=0xYYYY (Replace with your vendor id and product id)

now create new connection for tata give dial number and user password etc. enjoy!

If everything works, execute sudo gedit /etc/modules

Add the line usbserial vendor=0x**** product=0xYYYY (change vendor and product id as per your output), save and reboot.
