The APIs exist to detect a mouse and keyboard plugging directly into the console. In Rainbow Six, this is disabled.

There is not an API that our team, or any other development team, has been made aware of to detect third party adapters such as the XIM Adapter. These emulate controller inputs, and are regularly updated by their manufacturers to circumvent detection methods. As such, they are not detectable.
