    How do i fix USB Connector Manager with error code 43?


    Both of my USB-C ports are not working. I checked on device manager and saw yellow triangle on USB Connector Manager. Went to properties to see what was wrong and saw "Windows has stopped this device because it has reported a problemCode 43". Also " USCI PPM failed USCI command. Please contact USCI device or system manufacturer to investigate". What happened and how can i fix it?

    :)

    USB SuperSpeed error code 43

    Win 10 ver 1709.

    Device Manager always reports the SuperSpeed has a problem.

    I have tried uninstalling, updating drivers and a Win 10 online reinstall (repair upgrade?). No change. I installed Win 7 to a spare drive and it finds no USB problems. Also, in Dev Mgr, Win 7 does list a SuperSpeed.

    I attached snips of USB Tree and Dev Mgr under Win 10 & Win 7.

    I want to make the SuperSpeed error go away.

    Thanks, everyone,
    Terry

    Code 43 USB device not recognised

    Hi Vishnu,

    Thank you for posting in Community, we understand your concern and we will try our best to help you resolve the issue.

    Error Code 43 is a Device Manager error that means the following:

    Windows has stopped this device because it has reported problems. (Code 43).

    When you get this error with USB devices it’s because one of the drivers controlling the device notified the operating system that the device failed in some manner. This can be because of corruption in one of the loaded drivers and the driver cache just
    needs to be flushed. An alternative to resolve this issue is to perform
    Power Drain    , to do so follow the steps below

    • Unplug the charger and remove the battery of your laptop, if using a desktop remove the power cord.
    • Press and hold the Power button for 30sec.
    • Plug the charger/power cord and restart system

    I would also suggest that you refer to the Microsoft Article provided in the link below for more troubleshooting methods

    Hope this information helps.
