How did you manage to get the replacement driver installed? I have uninstalled all the drivers on the SD host controller/adapters but after every reboot or when scanning for hardware changes the drivers just reinstall. There is no option to delete driver files when uninstalling either. I tried downloading software to delete driver packages but this hasn’t worked either. I cannot see how to replace the pre-installed non working driver with the older unsigned one (linked above) that apparently fixes this sd card issue. I know how to install the unsigned driver but cannot get near that stage as I cannot uninstall the existing drivers or update over them (Windows determines the best driver software is already installed). grrrrr lol
