Windows 7: Problem with my SD card reader

I recently bought a intel Core i5 pc online and it came with the internal 12in1 flash media reader/writer. From what I know it is a generic name brand, so I don't know exactly which company makes it. It is connected to the motherboard. But when I plug in my Compact flash card and SD card to it, it doesn't read at all.

I am using windows 7 Ultimate 64bit version. Does anyone know where I can get those generic driver for that internal card reader?

I had the same problem with Windows 7 Home Premium 32-bit OS. I fixed it by downloading and installing USB card reader driver for Win XP/Vista/Windows 7 Driver (32/64 bits) Driver only (ZIP file) from http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=15&PFid=25&Level=4&Conn=3&DownTypeID=3&GetDown=false
