Generic Device: Logitech Headset

I'm attempting to set my new headset up as a generic device in BTT but am getting lost.

Previously, I've connected my PS4 controller, and in the input/output analyzer, I was able to see the individual hex-values changing as I pressed a button or moved my joysticks.

With my headphones, nothing auto-displays in BTT's i/o analyzer when I press buttons on them. I am unfamiliar with the code needed to manually parse this information- if that is the only thing I need to do, could someone point me towards information on how to do that?
