Try seeing in Devices and Printers.
The problem is that the data cards contain a small amount of flash memory that hold the drivers
and they are set to be emulated as CD drives.
Since they emulate CD drive, they autorun the driver
installation without user input.
That is the reason why Sunil's screenie shows The CD Drive under his mobile.
Hope this helps.
P.S.: Post the screen of devices and printers and also take a screen shot with right click menu of your mobile.
