All-in-one Nintendo Switch 1/2 Pro Controller on PC solution

Download · Website · FAQ · Contact

---

The Switch 2 Pro Controller does nothing when you plug it into a PC - it waits for a proprietary activation sequence that only the console normally sends. connectyourpro performs that activation automatically and turns the controller into a standard Xbox 360 (XInput) or DualShock 4 gamepad that every PC game understands.

Features

• Switch 2 Pro Controller over USB and Bluetooth
• Switch 1 Pro Controller over USB and Bluetooth
• Built-in activation based on procon2tool
• Shows up in games as Xbox 360 (XInput) or DualShock 4 - switchable in the app
• Live controller test view
• Button remapping
• DSU server (Cemuhook protocol) - gyro/motion for Dolphin, Cemu and other emulators

Installation

1. Grab connectyourpro-setup from the latest release.
2. Run it - the installer also sets up the ViGEmBus driver (required for virtual gamepads) if it's not present.
3. Launch connectyourpro, pick your controller, connection and output type, hit Connect.

Bluetooth notes

• Pro Controller 2: do not pair it in Windows settings. Pick Bluetooth in the app, press Connect, then hold the controller's SYNC button until the LEDs sweep - the app finds it by itself. Bluetooth on the ProCon 2 is experimental and has noticeably more input lag than USB.
• Pro Controller 1: pair it in Windows Bluetooth settings first, then press Connect.

Building from source

Requirements: Visual Studio 2022 (Desktop C++ workload, Windows SDK), CMake.

build_release.bat

The executable lands in build\testapp.exe. The installer script lives in installer\connectyourpro.iss (Inno Setup 6; drop the ViGEmBus setup exe into installer\redist\ViGEmBus_Setup.exe before compiling).

FAQ

The "Pro Controller" entry in Windows game controllers shows random button clicks.

That's the physical controller - after activation it speaks a protocol Windows doesn't understand, so the built-in test panel shows garbage. Games use the virtual Xbox 360 Controller instead. Ignore the Pro Controller entry.

The controller stopped connecting at all.

These controllers have a built-in cooldown: too many connect attempts in a short time and they sulk for a few minutes. Wait a bit and try again.

No input after Connect (USB).

Unplug the cable, plug it back in, press Connect again. As a last resort the app has a fallback button that opens procon2tool in the browser.

Does it work with Steam?

Yes - Steam sees the virtual Xbox 360 / DS4 gamepad like any other controller.
