Teensy 4.1 - USB Device on the USB Host port

Does anyone know if there is an example out there of somebody using the USB Host port as a USB Device? Paul referred to someone (WZMX) possibly doing this but I'm unfamiliar.

My goal is to have the primary USB device port left as a "device port" for programming and debugging while using the "host port" as a USB Device to communicate with a PC, potentially using Raw HID packets for passing data. I'd hate to be a trailblazer if I can avoid it.

EDIT: The 2 separate USB device ports will be connected to different machines. One to a development computer, one to a computer that's part of the final application. This is why I can't just use one USB port with a combination of interfaces (ie., RawHID + Serial).
