Install a high speed USB host controller

When connecting a USB 2.0 device, Windows displays the following message:

The thing is
I DO HAVE A USB 2.0 HOST CONTROLLER
and I used to enjoy high speed using my USB ports, until I did some hard disk resizing, which I believe have nothing to do with USB ports.

Anyway, to solve this:
  • Open the device manager. In Windows 7, right click on My computer -> Manage.
  • In the Device Manager, double-click on the "USB Root Hub", then uncheck "Allow the computer to turn off this device to save power" 
It gave me a better speed, but not quite as the one I used to have.

If I find a better solution, I will to update this.
