Gcn adapter not detected OSX

[WhiteHotTippaToe]

I recently purchased the Nintendo switch GCN adapter for dolphin and for some reason it doesn't work. When i first plugged it in it worked like a charm. But now it will not detect. I have tried downloading the smash enabler and it hasn't done anything. If anyone can help me with this issue, feel free to add on. Thanks. P.S. - Im running the latest update of OS x High Sierra
