Uninstall the driver from Add/Remove Program and restart your PC and plug it in again. –  user80881 May 12 '11 at 5:49

BSNL does not manufacture datacards, you need to check who is the manufacturer of the device and then you might find the driver on the manufacturer's website.
BSNL has a driver on its site, you can check it. It might be the one you are looking for.

When you plug it in, it should appear as a CD-ROM drive in Computer. If you click on that icon you should see an install.exe, which will reinstall the software.

(I'm not sure if I am getting confused with MTS, as I was using both on a recent trip to India, but they both worked similarly, as far as I can remember)

When i connect my Data Card nothing comes inside MyComputer, i mean neither in a Removable drive nor CD-ROM drive. –  Ishan Jan 3 '11 at 7:46
