Chronus can be detected on consoles, just not super easily. And it kinda depends on each game's developer and their ability to implement such detections. I know that Embark Studios have said that they've found ways to detect such devices in The Finals.

I believe that, while they can't detect the actual hardware plugged into the console, they're able to detect input patterns that would only be possible from M/K (such as 0ms AD-spamming). Of course, I can't imagine that's 100% foolproof on its own, either.
