I recently downgraded my HP Pavilion TouchSmart 11-e015dx Notebook from Windows 8 to Windows 7. Only Windows 8 drivers are listed under the support page, but they all seemed to install and work just fine. The only problem is that my right two USB 2.0 ports don't work after Windows loads up. There aren't any drivers under the support page and Windows Update can't find them, nor can several driver update programs - It's just listed as an unknown Universal Serial Bus (USB) Controller under the Device Manager.
Any idea where I might be able to get those drivers?
