Why my keyboard and mouse are out of work at AMD A320AM4 Motherboard
Question
Why my keyboard and mouse are out of work, when I attempt to install Windows 7 on LIVA MINI PC / Skylake, Kabylake, Braswell and AMD Ryzen AM4 Motherboard?



Answer
The main reason is Windows 7 using EHCI structure which are incompatible with XHCI structure on Skylake, Kabylake, Braswell and AMD Ryzen AM4 platforms. Therefore, USB 3.0 is out of work when you attempt to install Windows 7 on platform.

What I think happened

I believe the maintenance tool “cleaned up” the drivers for your mouse and keyboard.

In other words, it removed them and replaced that software with something else — something that obviously doesn’t work.

I can’t really say why it did so. Perhaps it mistakenly thought the driver software was malicious. Perhaps, as a performance optimization, it thought there was a better choice. Perhaps it just screwed up.

Either way, it made a mistake. There’s too little to go on to say whether that’s serious enough to stop using that tool. If it makes mistakes like this consistently, of course, I would look for an alternative.

Try a different mouse and keyboard

First, I would try a different mouse and keyboard if you have some lying around.

While it’s more likely this problem affects all USB mice or keyboards, there’s a chance it doesn’t. If so, and these replacement devices work, this makes interacting with the computer significantly easier. You can still try some of the steps below to restore your original devices’ functionality, but as you’ll see in the next steps, at least you can do so relatively easily.
