In Device Manager, double click to expand Universal
Serial Bus controllers, right click on the Host Controller, click Uninstall and click OK.

Rather doing a driver hunt
which can take hours
it might take some time being a freeware driver solution

This will automatically search for and find the correct driver you will have to
update every driver individually once you update you might be asked whether you
want to restart or make a system restore point.
Click no to both of these then continue updating each driver free then restart
once all of the drivers have been updated.
