I just purchased an Inspiron N7110 laptop and I did a clean install of Windows 7 Utlimate 64 bit and everything is functioning properly with the exception of the USB 3.0 ports.  In the clean install, I followed directions in terms of the order to install drivers and I got the drivers from dell.com.  When I installed the driver for the Renesas USB 3.0 Host Controller, the install appeared to work but I got a balloon type windows message immediately following the install indicating that the device driver software for the USB Controller was not properly installed because no driver was found.  In device manager, there is an entry under Other Devices for Universal Serial Bus (USB) Controller with a yellow exclamation point next to it.  Also, under Start/Programs, there is an entry for USB3 USB Host Controller Utility but when I try to open this I receive a message box with the following message "USB 3.0 Host Controller Not Found".  After I reboot, nothing changes in the device manager or when I try to open the USB Host Controller Utility program.  So the bottom line is that the USB 3.0 ports do not function with either USB 2.0 or USB 3.0 devices.  Any help on this is appreciated.
