DualSense Reverse Engineering

This post documents a teardown and reverse engineering of the PS5 DualSense controller, showing how to read HID reports over USB, map button bytes, and send commands to control LEDs, haptic actuators, and the speaker. The author integrates these capabilities into the Dual-Pod-Shock project to play music and trigger functions via button presses, resolving audio stutter by converting MP3 tracks to SBC with specific GStreamer parameters. No cybersecurity incident, malware, or threat activity is described.
