Turn off all USB peripherals connected to your motherboard and check if the warning persists. If present, examine the board and detach the internal USB connectors. Should that fail, provide images of each USB connector; it may indicate a faulty motherboard. If the first attempt succeeds, reinsert devices sequentially and test again—potential issues could stem from a bad keyboard or other hardware faults.
