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
- Grab connectyourpro-setup from the
latest release.
- Run it - the installer also sets up the ViGEmBus
driver (required for virtual gamepads) if it’s not present.
- 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.
