If not, then find another KB and use that. My system would not load the mouse until I unplugged it and plugged it back in, but in order for Windows to load the drivers, it has to get past that screen. So try any other KBs you have, safe mode is not going to help cos the drivers still have to load, or possibly be downloaded. If you have a PS-2 KB input, try a PS-2 KB, that will get you past this, after a few reboots your system will have the right drivers loaded and this will stop.
If your KB and Mouse are IR, there should be a connect button that connects them to their base station, check that too. You may just have to find a cheapy KB and mouse to get you past this, once the Logitech drivers are installed, then they will work every time.
I really appreciate all the help.
I'll try to look up the commands you speak of.
I'm primarily a gameplay software engineer for unity3D.
I have tried three keyboards and three mice, all usb. I don't have a PS-2 anything any more. I tried lots of combinations of unpluging/plugging things in at different times and ports. Nothing gets powered. I verified that all of my devices are working correctly on other computers. Its like the Windows 10 isn't recognizing my motherboard. Its an Asus motherboard from a few years ago, a reasonably good one.
One mice and one keyboard are pretty basic generic keyboards. Was considering buying yet another basic keyboard tho.
I am not sure if it makes a difference, but I had two monitors hooked to my graphics card. I was wondering if that was causing a issue so I also tried different combinations of plugging in monitors to no avail.
I am probably using the exact same MB as you are using, it's an Asus M2N-SE Mb from around 2006, and the only problem I really had was with my MS Mouse, it would not detect.
I have noticed that MS systems are crappy when it comes to USB driver support, I've had similar problems in Windows 8 too. You are basically stuck until you can log in, and you can't log in with the USB input devices.

Will he be able to get to that account if his Lockscreen is jammed up? Let me know if that worked. But I'd borrow a PS-2 KB from someone just in case.
