I have recently tried to use my CAC reader on my Windows 11 and have experienced issues. I have been able to use it before, but not until recently it gave me problems. When opening me device manager, it says code 31 error.

    Hi @Ismael urrutia

    After a restart, Microsoft Usbccid Smartcard Reader is in a problem state with a yellow bang and this error is displayed in the device status:

    This device is not working properly because Windows cannot load the drivers required for this device. (Code 31)
    {Operation Failed}
    The requested operation was unsuccessful.


    During initialization, the smartcard driver attempts to create an instance of smart card class extension. The attempt failed and the driver isn't loaded.


    To ensure a successful driver initialization, add the RetryDeviceInitialize registry key and restart the computer.


    The registry key is available for Windows 10, version 1903 (19H1) and later versions.

    Name: RetryDeviceInitialize
    Type: DWORD (32-bit)
    Data: 1
