3. After finishing the uninstallation, restart your PC then Windows will reinstall the device automatically.

Solution 2: Update the Generic USB Hub Drivers

Follow these steps:

1. In Device Manager, under category “Universal Serial Bus controllers”, right-click on Generic USB Hub device and select Update Driver Software…

2. Select Browse my computer for driver software.

3. Select Let me pick from a list of device drivers on my computer.

4. Check the box next to “Show compatible hardware” and select Generic USB Hub. Click on Next button.

Then Windows will update the driver software for the device. If it is done successfully, a window will pop up like this.
