Programs that claim to update your drivers install either the wrong or corrupted drivers.
If you have installed any driver with Driver Booster 3, please remove them as it may cause trouble.
Update the USB drivers from Asmedia, if it doesn't help use different USB ports to connect mouse/keyboard on and see if that helps.
