    NB: ignore_ctl_error=1 may help when you get an error at accessing

        the mixer element such as URB error -22.  This happens on some

        buggy USB device or the controller.

    NB: quirk_alias option is provided only for testing / development.

        If you want to have a proper support, contact to upstream for

	adding the matching quirk in the driver code statically.
