To fix this issue, you need to verify that an IRQ has been assigned to the USB controller in the computer's BIOS.
Key Takeaway: USB Root Hubs are both physical and virtual installation ports that can be found on your computer. In this case, the root hub may be improperly configured. USB controllers require that an IRQ be assigned in the computer's BIOS. If the controller is not properly configured, you will see the root hub displayed in Device Manager with a yellow exclamation point.
