    Unknown (nonexistent) USB Issues


    Would anyone know what might be causing "unknown" and non present devices? The devices continually reinstall themselves, even after being uninstalled?
    Below is a small snapshot of the Device Manager.

    I only have a keyboard, mouse and external drive in use.
    nothing more is connected via USB.
    Yet those three unknown devices keep showing up?

    Any questions or suggestions, about this would be great.

    :)

    Hi Ali,

    In most cases, this issue can be caused by either an unstable/ corrupt USB controller or your computer's drivers need to be updated.

    For us to isolate the possibilities, we suggest that you perform the following troubleshooting steps in succeeding order:

    • Connect your USB drive to a different port. Alternatively, try to connect it to a different PC.
    • Connect a different USB drive to your PC.
    • Unplug your USB drive and restart your system. Afterwards, plug it in and see if it works. If the same issue occurs, perform a complete shutdown and wait for a few minutes before turning it on again.
    • Update your drivers.

    If you find that the USB drive still doesn't work even after performing all these suggestions, this is most likely pointing to a hardware issue. Thus, it would be best to get in touch with your device manufacturer for a thorough check of the device.

    If you have any other questions or concerns, feel free to post back and let us know.

    Thanks for the response but there was not a problem. It was because of me being stupid. I had too much clutter around my PC and I had connected my external drive and thought It was my external storage device. I found out that my some USB connections did
    not work on my old laptop. That is why I received the "Unknown device message." Sorry and thank you for the quick response.
