Everyone has "root hubs" if you have USB ports. Check in device manager
(driver details) and you will see this is so.
Start by disconnecting ALL of your USB devices. Create a drawing as to what
is connected where. You will want to eventually reconnect them to the same
port.
You may have to get hold of an older PS2 mouse and keyboard if you don't
have one now.
Then turn off the computer and plus in one device at a time. Connect each
physical device to the same port it was originally connected to. If you do
not have a defective device it could be a defective port. Test with each
successive device until you find which combination causes the error.
