So i have the Broadwell NUC above and when i install the Win7.1 USB3.0 drivers, i then cant use USB anymore.
I've done this twice, once installing the USB3.0 drivers from the Win7.1 64 bit download first and then again after installing chipset, network, bluetooth etc.
Same result. No USB after these drivers are installed. (I'm just using a USB keyboard and mouse which are 2.0).
