I downloaded the drivers from [URL] unpacked it and told it not to install the drivers ( didn't want to install Lenovo software ) then from Device manager updated the drivers, pointed to where the files were unpacked and Presto..card reader is working :emotion-2:  
All of you who can't find driver for this device. This is card reader. Find realtek card reader drivers for your notebook . Cheers !
