After installing the Windows 10 2004 update I lost both my keyboard and mouse. Discovered this is due to a USB 2.0 issue. Connecting the kybd / mouse to USB 3.0 ports on an expansion board allows them to operate with no issue. I cannot boot my system this way, have to move the keyboard to a 2.0 port for boot-up then back to a 3.0 port for Windows.
My system is an older Dell tower, Intel(R) ICH10 Family USB Enhanced Host Controllers. In Device Manger the USB Host Controllers, Root Hubs, and Composite Devices all show to be OK. Only the Universal Serial Bus (USB) Controller lines indicate an issue. The properties page says to 'Reinstall the drivers for this device. (Code 18)' I've had Windows search my drive and the web for updated drivers. No updates found and failures each time I try to reinstall the current drivers. BTW, I've uninstalled all the USB ports and Root Hubs, rebooted the system, same conditions afterward.
USB memory sticks seem to work OK in the ports, only the keyboard and mouse are affected. And the keyboard works OK in a 2.0 port prior to Windows loading.
