Thanks for the comment. There is only one available device for most users, so
the default one and the given one from user should be the same, otherwise it
won't work. I don't want to make them in trouble if they don't have a driver to
support the new interface. However I agree with you it is a little evil to
ignore the request. I'll update the patch to return error here.
