All-Input-To-Photon Latency metric and game controllers

[Aaron1017]

Scenario:
I play about half my PC games using an official Xbox controller or a 3rd party controller.

Problem:
PresentMon does not recognize game controllers as "all input" and the graph does not work. "all input" only appears to recognize keyboard and mouse input.

Feature request:
Update PresentMon to recognize XInput devices so the All-Input-To-Photon Latency metric will work for controller users.
There is also the legacy "DirectInput" method, but its rarely used anymore. XInput would cover the majority of users.
