Drivers Windows 7 USB Controller

Recently, I went down my HP Pavilion TouchSmart 11-e015dx notebook from Windows 8 for Windows 7. Only Windows 8 drivers are listed on the support page, but they seemed all to install and works great. The only problem is that my right two USB 2.0 ports do not work after Windows loads to the top. It is not all the drivers on the support and Windows Update page cannot find them, nor can many programs update driver - it is just seen as a Serial Bus controller universal (USB) unknown in Device Manager.

Any idea where I might be able to get these drivers?

Hello:

Please download and install the driver from the chipset AMD and restart.  The first file listed.

On some of these very new PC, AMD USB controller drivers install automatically for one reason or another.

If this happens, please read my solution and workaround for NAP_CHL_IT on the link below and try these two.
