I'm a bit confused. Can you give more details about your setup and how things are connected? What controller are you using and what's wired to what?

There can only be one controller, and it doesn't need to discover itself or respond to any PIDs (It already knows everything about itself)

The Enttec USB boxes can be configured to run as an RDM Controller, or as an RDM responder (but they can't do both simultaneously). It sounds like yours might be configured to act as a responder. The ACK Timer behavior is common for USB-attached RDM Responders since the host computer can't guarantee it will respond within the 2ms response window.

I've only used the older Enttec USB boxes and you had to explicitly configure them to be a controller or a responder. It's possible that the newer NK2 units can auto-switch.
