Thrustmaster eSwap Pro Tester
Connect a controller and press any button — every input is detected and displayed live.
Connect a controller and press any button
Browsers hide gamepads until first input. Plug in via USB or pair over Bluetooth, then press any button to wake the test. On phones, pair the controller in your system Bluetooth settings first.

Rotate a stick around its full rim — we trace the path against a perfect circle.
How it works
The Thrustmaster eSwap Pro's headline feature is hot-swappable modules — you can pull and replace a stick or D-pad module without powering down, and it re-registers instantly. That live-swap ability creates a unique, harmless testing quirk in the axis order.
How to connect your Thrustmaster eSwap Pro
Wired USB-C only. Hot-swappable modules re-register instantly — you can swap sticks mid-test.
How the Thrustmaster eSwap Pro maps in your browser
Wired USB-C, it maps to a generic/standard layout. After a hot-swap the browser occasionally reports the axes in a shifted order until you reconnect — expected behaviour given modules can change mid-session.
Thumbstick type and drift risk
Swappable potentiometer stick modules. Because a stick is a replaceable module, a drifting stick is a quick user-swap rather than a repair.
Wired USB-C only.
Known issues and quirks
After a module hot-swap the axis order occasionally shifts until reconnect.
Once connected, press any button and the tester will detect the pad automatically. Check every button and trigger registers, watch the stick crosshairs for centering, and run the circularity test to quantify stick wear. Suspect drift? Run the dedicated controller drift test for a 10-second automated verdict.
Testing every part of your controller
Browsers hide gamepads until you press a button, so tap any button once to wake the connection. From there, every button, trigger, analog stick and (on supported hardware) vibration motor is displayed live. It works with anything your OS recognizes as a gamepad — Xbox, PlayStation DualShock 4 and DualSense, Switch Pro, and most generic USB or Bluetooth pads.
What to check, and what's normal
| Element | Healthy behavior | Warning sign |
|---|---|---|
| Face & shoulder buttons | Register instantly, release cleanly | Sticky, missed, or double inputs |
| Analog sticks (at rest) | Under 1–2% jitter around center | A constant offset = drift |
| Triggers | Smooth 0–100% travel | Jumps to 100% or won't reach it |
| Vibration | Rumbles on command (Chromium pads) | Silent on Safari/Firefox = browser limit, not the pad |
Troubleshooting connections
- Nothing appears: press any button first; if still hidden, try another USB port or re-pair Bluetooth and reload.
- Layout doesn't match your pad: unknown models fall back to a generic view, but every button and axis is still shown by index — you can fully test it.
- Vibration does nothing: rumble over the web works on Chromium browsers with most Xbox and DualSense pads; Safari and Firefox have limited or no support.
If the sticks jitter beyond a couple of percent at rest, run the dedicated controller drift test for a measured verdict.
Troubleshooting
› My controller is connected but nothing shows
Browsers hide gamepads until you press a button — press any button once. If it still doesn’t appear, try a different USB port or re-pair Bluetooth, then reload the page.
› Vibration test does nothing
Vibration via the browser works on Chromium browsers with most Xbox and DualSense pads. Safari and Firefox have limited or no support — that is a browser limitation, not your controller.
› The layout doesn’t match my controller
Unknown models fall back to a generic layout. Every button and axis is still shown by index, so you can fully test the pad even without a matching picture.
Frequently asked questions
› Which controllers are supported?
Anything your OS recognizes as a gamepad: Xbox (360/One/Series), PlayStation DualShock 4 and DualSense, Switch Pro, and most generic USB or Bluetooth pads.
› Do I need to install anything?
No. The test uses the browser’s built-in Gamepad API — just connect your controller and press a button.
› Why do axis numbers jitter slightly at rest?
Analog sticks always have a little electrical noise, typically under 1–2%. Constant offsets beyond that suggest drift — run the dedicated drift test.
› Can I test controller vibration?
Yes, on Chromium-based browsers with supported pads. Click the vibration button; if nothing happens, your browser or pad doesn’t expose rumble to the web.
Common Thrustmaster eSwap Pro problems and how to read them
These are the faults reported most often for the Thrustmaster eSwap Pro, what causes each one, and how to confirm it in the tester above before you spend money on a repair or replacement.
| Symptom | Cause | What to do |
|---|---|---|
| Axis order shifts after swapping a module | Live module hot-swap re-enumerates inputs. | Unplug and reconnect the pad to normalise the axis order. Not a fault — it's the cost of hot-swapping. |
| A stick module drifts | Potentiometer wear in that specific module. | Swap in a fresh module and re-run the drift test; a clean reading confirms the old module was the culprit. |
| A swapped module isn't detected | Module not fully seated. | Re-seat until it clicks and reconnect. Confirmed working once its inputs appear in the tester. |
Testing tip: Use the tester to A/B two stick modules back to back — swap, reconnect, and compare drift-test deviations to decide which module to keep in play.
