USB mouse and keyboard unplugged, and now do not work

I unplugged my USB Kensington keyboard and Anker mouse to use on another computer. When I plugged them back into the first computer, they were not detected.

I restarted the computer, no help. BIOS says USB detection enabled. I uninstalled the Anker driver and reinstalled to no effect.

Strange part is when I plug in a spare Dell mouse and Microsoft keyboard, my computer detects them and let's me use them.

The Kensington keyboard and Anker mouse do light up when plugged in, but are unusable. They work when plugged into the other computer. I am perplexed. Ideas?

Are the drivers installed correctly?

As far as I know.

Open your device manager and see if there are any errors

When I plug in the nonworking keyboard and mouse along with the working keyboard and mouse, it detects the nonworking ones, but says they are unspecified. When you click on the properties, it says the devices are working properly, which they obviously are not. So perplexed.

I filled out the specs. Does that give you any insight?

Keyboard and mouse are connected to front USB ports (connected to rear USB before with same results).

Did you try to reinstall the drivers?

Yes, to no effect.
