USB 3.0 port not working on Asus X53TK (Solved)

Hi,
I am running Windows 7 - 64 bit but my single USB 3.0 port won't work.
If you are also one of the harried souls whose USB 3.0 port is not working on Asus X53TK, read on.. :)

My Asus X53TK for some curious reason did not show USB 3.0 host controller in Device Manager instead there was an "Unknown device" in SM Bus Controller. I tried all kinds of stuff - downloaded AS media driver, NEC driver, edited driver files to install Before fortunately arriving at the fix below.

(For Device Manager: Right click "My Computer". Click 'Properties'. Click Device Manager)

Step 1: Uninstall the pesky "Unknown device"
Just right click the "Unknown device" entry in device manager. Click "Uninstall". Click OK.

If you have installed ASMedia driver for USB 3.0 or NEC USB 3.0 driver. Please uninstall them too.

Step 2: Download Chipset_AMD_Compal_Win7_64_Z897300000 driver from Asus website (Link: http://support.asus.com/download.aspx?SLanguage=en&p=3&m=X53TK). It is a 215 MB zip file.

It is the latest Chipset driver for X53TK. (see pic below)

Step 3: Extract the zip file and run setup.exe from it.
It will install USB 3.0 Host Controller and your USB 3.0 port should start working.

Thank me, if it helps. :)
