I want to apologize in advance for my being a noob. Please be gentle. I would like to add a simple button box to give me more buttons while playing gt sport. I have a thrustmaster t300rs wheel and ps4 pro no computer involved. I'm new to this community, (enjoying my time in lockdown) and not racing online yet. I purchased a simple number box with usb plug but can't seem to figure out how to program it. On gt sport under options, it offers my specific wheel and you program the functions to the wheels buttons... Not sure how to add the additional box into its system. Any help you can provide would be greatly appreciated. Sincerely. Rotaxman
