DualSense Controller Test (Web HID)

Free browser-based diagnostic for the Sony DualSense and DualSense Edge controllers, plus DualShock 4 (v1 and v2). Reads input via Web HID over USB-C or Bluetooth and decodes the proprietary report 0x01 / 0x31. Visualises sticks with sub-pixel precision, shows analog trigger pressure as a percentage, lights up every button, and renders the touchpad with multi-touch support. No driver, no app — just desktop Chrome or Edge with the controller plugged in.

How to use

1
Plug the controller in

Use a USB-C cable for the most reliable connection. Bluetooth pairing also works once the controller is paired with the OS.

2
Open in desktop Chrome or Edge

Web HID is supported only in Chromium-based desktop browsers — not in Safari, Firefox or any console-side browser.

3
Click Connect

A device picker appears. Pick your DualSense, DualSense Edge, or DualShock 4 — the page switches to live diagnostic mode.

4
Walk through every control

Move both sticks in full circles. Pull both triggers to 100%. Press every button on the grid. Slide one and two fingers on the touchpad.

FAQ

Why does this work over USB but not Bluetooth?

Web HID does support Bluetooth on most platforms, but BT framing on the DualSense uses report ID 0x31 with a 1-byte prefix. The page handles both — if BT pairing is connected first, click Connect and the matching report layout is used automatically.

Can I set the lightbar colour or trigger resistance?

Yes. The output panels above let you set the lightbar RGB, player-LED bar, rumble intensity and adaptive-trigger profiles per side (off, rigid, pulse, vibration). The page writes the proprietary output report with the CRC-32 checksum required by Bluetooth framing — the controller responds in real time.

Does this work with the DualShock 4?

Yes. The page detects DualShock 4 v1 (0x05c4) and v2 (0x09cc) and decodes the same input report shape. The touchpad, sticks, triggers and most buttons all work.

My controller is recognised but no input shows.

You may have Steam Input running and intercepting reports. Close Steam (or set the controller to ignore Steam Input) and reload the page. On Mac, a similar issue can come from PlayStation Now / PS Remote Play apps.
