General • Seeking help: Implementing Dualsense ↔ RP2040 ↔ PS5 passthrough

Hi everyone,

I’m working proof of concept to connect an original Dualsense controller to a PS5 using an RP2040. The goal is to enable features like buttons combination, remapping, and turbo while maintaining compatibility with the PS5’s security checks.

Here’s the high-level flow of the idea:Dualsense Interface (USB Host Mode): RP2040 acts as a USB host to capture input data from the Dualsense.
Processing Logic: Features like button combinations, remapping, and turbo.
PS5 Interface (USB Device Mode): RP2040 emulates a USB HID device to send inputs to the PS5.

The PS5 performs security checks to verify the connected device is an original Dualsense controller. The RP2040 must:

• Pass these security checks by accurately emulating the Dualsense’s USB descriptor and communication protocol.

• Return the verification handshake between the Dualsense and PS5 to avoid detection. Probably with USB Passthrough.

The basic implementation is clear, there are excellent TinyUSB and PICO-PIO-USB libraries for this.
I have found different community developments in this area, including the excellent GP2040-CE, but I have not found a similar solution.

Current issues on implementing USB Passthrough on RP2040:

• Has anyone idea how to implemented USB passthrough on RP2040 to handle bidirectional communication between Dualsense and PS5?

• Are there libraries or examples for USB host/device mode with USB passthrough that could help?

• Is there a way to intercept and return the verification handshake between the Dualsense and PS5?

I’d love to collaborate with anyone interested in this project or who has experience with RP2040. Any advice, resources, or shared experiences would be greatly appreciated!
