I don't have any documents/drivers. At a recent project in Arizona i installed my first/only Amazon Fire TV box. I had done some IR control research myself assuming it would be IR but then the programmer handled it with IP control.
This article at CEPRO talks about a company that has a driver.

This is a good thread about IR control.
