I have recently bought a new Sony Vaio VGN-FS980 model laptop which is running on Windows Vista operating system. I have successfully installed all the drivers in this laptop, but there is this one driver for the mass storage controller that I couldnt find anywhere. When I checked in Device Manager then there was yellow exclamation mark next to the Mass Storage Controller and Unknown Device. Please help me to find the drivers for this devices. Thanks in advance for any help.
