Fix “USB Device Not recognized” / Code 43 Error

    I encountered this error on 2 different computers. All but one of my USB devices would work, and the port I plugged it into was fine, because other devices worked with it.

    There were many posts about how to fix this issue on the internet, but none of them worked for me. I stumbled upon my own answer based off ideas of uninstalling the USB Controllers (close, but didn’t work for me). Try this simple fix below.

    1) Open Device Manager
    2) In “Universal Serial Bus controllers” delete all entries that are “USB root hub”. Unplug and re-insert any USB devices (mice or keyboard for example) that stop working, and when they’re active again continue uninstalling any remaining listings.

        Scan for new hardware in your Device Manager, it should re-appear.

      will this delete all the data on the USB?

      • Jonathan

        No, this does not delete data on USB drives. If you’re worried, simply unplug your usb devices before uninstalling the controllers.
