Recently, I installed Windows 8 in my Dell Inspiron n5110. After the installation my USB 3.0 port stopped working. I tried installing the driver but nothing is happening. When i click on the USB 3.0 Host Controller Utility, I get an error stating "USB 3.0 Host Controller Not Found!"
It was working fine before I installed WIndows 8.

I tried uninstalling and reinstalling it several times, still no success. I have the NEC USB 3.0 driver.

Please help me!
