I recently posted this thread for which it appears that help is in short supply. Quickly, that thread was triggered as a result of using the Xpress Install that came with my new Z270P-D3 motherboard. Using the Xpress Install seemed to work but the Windows 7 system that resulted had the mouse and keyboard becoming inoperative shortly after booting the system.
As a result, I think it is necessary to incrementally install the drivers and test the system after each one. Presumably that approach would allow the driver install file that is causing the above problem to be identified if the problem persists.
However, I've now discovered that none of the USB 2 ports seem to allow the connected USB device to be recognized by the running system. I have a USB 3 front panel device on order but it is NOT available now.
What is especially interesting about this predicament is that I can boot the computer just fine from those same USB 2 ports. For example, when I boot WinPE it starts up and runs just fine but in a similar manner it does NOT recognize the existence of the USB device used to boot the running system.
I'm new to this motherboard which especially means that I'm NO expert when it comes to BIOS settings. I thought I should be able to get my replacement system up and running before turning my attention to learning whatever BIOS details I might be interested in knowing about.
I'm sort of thinking that if I'd messed something up when assembling the computer that such USB devices would NOT be able to do anything. The idea that they work fine for booting suggests that this problem might be caused by some BIOS setting/s. Any ideas would be greatly appreciated.
Note: My keyboard and mouse are connected via those same USB ports and they seem to work fine as long as I have NOT installed the drivers associated with the motherboard. My idea to install them individually pretty much needs properly functioning USB ports.
