I have Micromax 3G modem, and I inserted it in the USB port, but it is not being detected by Ubuntu 12.04, that I'm using from a Live USB. I tried creating a mobile Internet connection, however, eventhough I created it, there is no option to connect. 

I had previously used 11.10 Ubuntu, and it had automatically detected the datastick modem and asked me to create a connection. 

On typing `lsusb` in the terminal it gives the following:

```
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

```

tried to insert the modem before boot, with negative results
