    Hi and thanks for your reply.

    The Quartus version I'm using is 18.1.1 Build 646 04/11/2019 SJ Lite Edition

    I tried to update the driver but I got the message "The best drivers for your device are already installed"

    I tried when both the device was recognized and not recognized (please see attched)

    Regards
