Problem 2: Rumble not working in RetroArch

Cause: RetroArch uses udev or sdl2 driver which may not enable force feedback for unknown VID/PID.
Fix: In RetroArch, go to Settings → Input → RetroPad Binds → Port 1 Controls → Device Type → Change to “XInput” or “Stadia Controller” if listed. Alternatively, compile RetroArch with -DHAVE_HID=ON. Problem 2: Rumble not working in RetroArch Cause

Endpoints

• Interrupt IN endpoint: Interrupt transfer, typical interval 1–8 ms, max packet size matching report size (e.g., 12).
• Optional Interrupt OUT endpoint: for force feedback or LED control.

Key points from user reviews (post-Stadia shutdown):

Pros:

• Solid build quality – feels premium, similar to Xbox controller.
• Low latency over USB – works as a standard HID gamepad on PC, Steam Deck, Android, and Raspberry Pi.
• Comfortable ergonomics – good for long sessions.
• USB-C connection – no batteries needed (wired mode).
• Works with Steam Input – fully mappable.

Cons:

• Bluetooth mode is limited – originally for Stadia; now can be switched to standard Bluetooth but requires manual firmware update (Google released a tool).
• No wireless dongle option – unlike Xbox controllers.
• No rumble / vibration over Bluetooth – only works in USB mode.
• Back/paddle buttons missing – not for competitive gamers needing extra inputs.

USB Vendor IDs are not random. Google’s other VIDs include:

• 0x18D1 (Android devices, Nexus/Pixel phones)
• 0x22B8 (Motorola)
• 0x1949 (Stadia, Chromecast, some Nest devices)

The number 1949 is believed to reference the founding year of the People’s Republic of China – a coincidence or a deliberate nod to manufacturing partners? No official statement exists. However, PID 0402 is unequivocally the Stadia Controller’s first USB profile.

• -vendor excludes pages containing the word “vendor”
• -product excludes pages with “product”

This is a high-intent technical query – someone has already identified the device via lsusb and wants documentation, drivers, or fixes, not a store page. If you’re reading this, you probably already own the controller and want to make it work on a non-mainstream OS.
