Hi,
You can try the following:
- An external keyboard (in case of a laptop) or a keyboard from another vendor (in case of a desktop)
and/or another mouse from a different vendor could help. Perhaps a Bluetooth keyboard/mouse might also help.
IF it is a general USB problem, you could try a PS/2 keyboard (if you have the ports for it).
2)Try to get into the Windows Recovery Environment (e.g. by holding the power button during the boot logo and forcing a hard shutdown, this will trigger the recovery environment). From here you can select a System Restore Point and go back to the previous driver state.
The Recovery Environment has its own set of drivers, and it is not affected by Avast Driver Updater.
Remember that during boot, you will have to force a shutdown (holding down power button).
That should get you to the “Starting Windows Repair” message.
If that does not work, then you need to hold down the power button during boot again. It is a bit forceful but it will get you into WinRE.
From here you can choose the System Restore Point (in that environment, Windows-only drivers will be loaded, not any new drivers)
If the USB ports do not work in WinRE, then it’s a hardware defect.
