What is the brand and full model number of the laptop you're working with?

It's not laptop, IBM ThinkCentre E50 BORA-RH.
And I could not find model no.

"S/N" L3C7245" is written at the bottom of the case.

Using that model or parts of it returned only laptop items, very strange.
Look in Device Manager for yellow triangle on devices. Right click then and click on Update driver.

If that fails, do the same and choose Uninstall for each of the USB devices and then reboot, this is to see if Windows Update will find and install the correct drivers.
