last fix for the problem? Well, apparently
it's a super simple solution! No need to edit the registry, uninstall

that's it! Note that this does not mean just turning off your computer
because modern computers
don't really turn off when you
press the power button as the motherboard still gets power.
First to explain, the motherboard is where all of
hardware of the computer is connected to, including the USB

something can go wrong, i.e. all your USB ports suddenly stop working.
The small microprocessor on the motherboard will reload the drivers and
your USB ports should be back to recognizing all devices!
So first turn off your computer using Shut Down or pressing the power button and then UNPLUG it from the wall outlet. Let it sit for about a minute and then plug it back in.
