VirtualBox fails with "Implementation of the USB 2.0 controller not found" after upgrading

Download and install VirtualBox extension pack from here(according to your VirtualBox version). It may solve your problem.

Because your error report says like that.

To fix this problem, either install the 'Oracle VM VirtualBox Extension Pack'

I tried to install a virtual machine with windows XP and had a similar error. So i deactivated the USB controller and the machine is working now.

Maybe this will help someone.

start virtualbox -> right click on a machine (the machine should powered off) -> settings and now look on the screenshot enter image description here

there you can enable/disable it.
