via usb extensible host controller driver windows 7

I just can't get the USB 3.0 speeds I got under Windows 7. In my case, the eXtensible host controllers are being identified correctly. If the eXtensible controller is not being identified correctly on a system, something certainly needs attention. I was a little surprised by the New drive I got today because of the different type of connector. I have run 3 external drives/docks and all seem to work. No one, that I noticed, has really enumerated the USB devices they are having problems with. Commonalities might help narrow down the problem. And I notice some external devices also use that chip. It seems the VIA chipset has been mentioned in this thread several times. So, if it will not work after the OS is installed, then it might be something else. If you already know for sure that port will not work with Windows 7, then if the install continues beyond selecting Install and maybe the Key entry with Windows 8, you know your system is capable.

To test, I would put a USB 2.0 flash drive in a USB 3.0 port then try to install Windows 8.

It might add another piece to the puzzle knowing this fact. I was wondering if it would be any benefit to test your system to see if it could use the Windows 8 Built-in USB 3.0 drivers.
