Maximus IV Extreme: Windows 10 drivers?

Level 7

While attempting to upgrade to W10 none of the USB ports were functional. The drivers for the host controller for each (Renesas and Intel) could/would not load because W10 said they would cause issues and W10 gave me an error code 48. "Error Code 48: The software for this device has been blocked because it is known to have problems with Windows when USB device is connected."

I checked the ASUS website and there were no drivers for W10 for the USB controllers, just W7.

I also checked the Intel and Renesas websites and no luck there either.

I also tried to force the driver using the compatibility mode while doing an install of the drivers.

I tried using Windows Update to search for a driver, but it kept saying the best driver was already installed.

These are the 2 controllers:
Intel(R) 6 Series/C200 Series Chipset Family USB Enhanced Host Controller - 1C26 (W7 driver is
Renesas Electronics USB 3.0 Host Controller (W7 driver is

The board has one combo PS/2 port, so needless to say, having no USB ports available is not an option. Is my only option to stick with W7 (which I reverted back to after 48 hours of trying) or find a compatible PCIe card(s) with USB 3.0 ports?

Are you saying the USB ports do not function with the drivers that Windows installs?


You'd think Windows would have some default drivers or generic drivers that would work, but nope. 😞
