This blog covers how to run the micromax 352g usb modem on ubuntu 12.04. The basic problem that arise is the device is detected as an usb device not as a modem.
So for that you have to configure it using usb_modeswitch which is installed by default or if you have an external internet connection via dsl then install the following packages....
usb_modeswitch::: sudo apt-get install usb-modeswitch
wvdial::: sudo apt-get install wvdial
if you are using ubuntu 12.04 download wvdial from the link below
download wvdial.deb
next fire up terminal and enter ...
$ watch lsusb
it will show something like this ...
Bus 002 Device 007: ID 1c9e:9605
which is your device, where 1c9e is the vendor id and 9605 is the device id...
make changes to usb_modeswitch configuration file...
$ sudo gedit /lib/udev/rules.d/40-usb_modeswitch.rules
nter some text below the line that said
LABEL="modeswitch_rules_begin"
It looks something like this :-
LABEL="modeswitch_rules_begin"
#Micromax MMX352G USB 3G MODEM
ATTRS{idVendor}=="1c9e", ATTRS{idProduct}=="9605", RUN+="usb_modeswitch '%b/%k'"
save and then exit the editor.
next create a new file using ..
$ sudo gedit /etc/usb_modeswitch.d/1c9e\:9605
and add the following lines....
