[SOLVED] USB Keyboard and mouse not working, but other USB devices work... PS/2 works fine

[Titanion]

Currently using a PS/2 keyboard and mouse, and they work just fine. But USB mice and keyboards no longer work, but the USB reads a USB 4GB Storage Flash Stick just fine.

I have tried several different mice and keyboards, and none work. Rebooting, of course, updated Windows 10, of course. Played with bios settings, with Legacy both on and off.

Added an additional USB port, using a different USB pins on the motherboard, and attaches to the back, and it works with the 4GB Storage, but not with keyboard and mouse.

Lights come on for the mouse, but it does not work. This was a motherboard where sometimes getting in to bios, I needed a PS/2 keyboard, but the USB keyboard would always work when Windows loaded up.

This is an old Biostar motherboard, set up in my garage so I do not have the model number handy at the moment. but it is running Windows 10 Pro with a Intel-Core2-Quad-Q8400 with 4 GB or ram. It is a strange model that has two DDR2 and two DDR3 memory slots. I am using 2x2GB DDR2.

It was my son's computer for a lot of years, but became a 2nd computer for friends and cheating at Minecraft or whatever he used to do . He had some autoclicker for his mouse. I was wondering if that somehow messed with mouse and keyboard drivers. But it looked like an exe fine and not something that was actually installed.

Thanks

This may work, or not. I have an idea that sometimes Windows gets very confused when USB2 devices get disconnected, moved to another port, re-connected, repeat... repeat... etc. A few times I've done this and it helped. Basically, the process is to remove all traces of the troubled device (in this case, both your keyboard and your mouse), then re-connect them and let Windows "discover" the "new" devices and add in their drivers.

1. In Windows, go to Device Manger. Go through the entire list (especially USB devices AND PS/2 or mobo devices) looking for the keyboard and any mouse. There may be several instances of each. For every one of them Disable and Remove it. When you've cleared them all out, back out of Device Manager. BEFORE shutting down, unplug them both. Then shut down.
2. Reboot with NO keyboard or mouse attached anywhere. You will get error messages that they are missing. This will force Widows to remove all references to those devices in its Registry. Shut down again.
3. Plug in the keyboard only and boot up. Windows will disconver the keyboard and install a driver for it. If the default driver is sufficient, that's all you need there. You only need a custom driver for special keyboards with extra features. Check that the system responds to the keyboard. Shut down again.
4. Plug in the mouse where you want it and boot again. Same thing - Windows should detect the "new" mouse and install a default driver. If that works and is sufficient, you are done. On a few occasions I had to update the mouse driver to a generic Windows driver for a wheel mouse, as opposed to a plain two-button mouse.
