Sony DualSense Wireless Controller for PlayStation 5

This is a fork aimed at better documentation and an extension of the parent project.

For some reason, there is hardly any publicly available documentation regarding the Dualsense controller. I have scraped through multiple sources, including:

• Google Android Dualsense driver
• DualsenseX
• Dualsense (Steam)
• This project

95% fleshed out explorer tool

My highly detailed Dualsense HID protocol

Findings

• Accurate/Legacy rumble:
  • Ds4Windows sets a different bit that seems undocumented. Immediately before the flag2 byte is a value different from the Accurate rumble.

  • Legacy common[flag2 - 1] = 0x02

    Accurate common[flag2 - 1] = 0x06

• Android Dualsense driver: https://android.googlesource.com/kernel/msm.git/+/9882769164efdf1f2e1673bce4be1d1092ed89b2%5E%21/

Hmm, out of luck.

You should hear something faint from the controller when doing a sound test

Open Firefox (it sesm to be the only one which works for this),

Play Blade Runner 2049

Turn the volume up

You should feel and might hear something.
