As far as we're aware the InterLink Plus works currently. We don't guarantee that it will continue to do so, however, as we're making no special effort to officially maintain support for it. So, use at your own risk.
I think csgill75 accidentally left out a word and meant to say "...they no longer support the Interlink plus and if for some reason an update breaks the ability to use that controller, they will not fix the issue."
