via usb extensible host controller update

So I went through all the System Devices and Universal Serial Bus Controllers in the list and updated all of them that mentioned Intel, chipset or USB, directing it to use the INF/driver files from the downloaded Intel® Chipset Device Software version 9. The readme had instructions for doing it manually through device manager but it did not correspond to the names of my devices. When I tried to run setup.exe it said 'This computer does not meet the minimum requirements for updating the software'. The one that gave me an error was listed as INF, Intel® Chipset Device Software version 9. So I thought I will try installing them again. I complained to Microsoft support about the USB problem and they suggested I install drivers from the motherboard manufacturer. A couple of them did not install and gave me error messages - I assumed they were not compatible with my machine. I did attempt to install all the relevant Windows 8 64 bit drivers from my motherboard manufacturer's website. Here is where I got mine - ASRock > B75 Pro3-M )Īfter upgrading from Windows 7 to Windows 8 (64 bit) my USB 3.0 ports would only operate as USB 2 ports - at slow speed and Windows would say 'device can perform faster if connected to USB 3' I had to get the inf/driver files from my motherboard manufacturer's website (Check your motherboard manufacturer's site. If you have an intel brand motherboard I believe you can just use this - Download Center (Try running the setup.exe first, it might work for you) At first I had trouble installing it, but using device manager you can manually update the Intel chipset and USB drivers one by one and point it to the folder with the downloaded inf/driver files. Intel® Chipset Device Software version 9.

It has fixed my problem, I hope it may work for other people too.

I found a solution that does not require unsigned drivers.
