Device Manager, USB 1.1 devices that are attached to the controller may stop functioning.
Due to the synchronization of the USB 2.0 controller and its USB 1.1 compatible controllers, the USB driver stack also removes the USB 1.1 compatible controllers when the USB 2.0 controller is removed. When the device driver update is complete, the USB 2.0 controller is restarted; however the USB 1.1 compatible controller remains disabled. Therefore, any USB 1.1 devices that are attached to the controller no longer function.
- In Device Manager, on the Action menu, click Scan For Hardware Changes.
- Restart the computer.
