    Hi All,

    I'm in trouble trying to use an MHS TinyCAN usb-dongle on Qt6.4.2 (MinGW 11.2.0 64bits)... the plugin is recognized and loaded, but no frames are received/transmitted, even when using the original example provided with Qt6.

    The same example works fine when using Qt5.15.2 (MinGW 8.1.0) in both 32 and 64bit versions.

    Below are some info reported when launching the application with the QT_DEBUG_PLUGINS env variable set.

    I'm not sure if the problem is somehow related to:

    qt.core.library: "C:/Qt/6.4.2/mingw_64/plugins/canbus/qttinycanbus.dll" loaded library
    onecore\windows\directx\database\helperlibrary\lib\directxdatabasehelper.cpp(818)\directxdatabasehelper.dll!00007FFD1A870150: (caller: 00007FFD1A86F979) ReturnNt(1) tid(4184) C00000BB Richiesta non supportata.

    any hints?
