Windows USB Driver

The editor requires the WinUSB driver for the Nord G2. If the app reports a USB driver problem, install it using Zadig.

Important: Run Zadig as Administrator (right-click → Run as administrator), otherwise it cannot replace or install the driver.

1. Open Zadig and select the Nord G2 device.
2. Choose WinUSB as the driver.
3. Click Replace/Install Driver.

Note: This replaces Clavia’s original USB driver. You will need to reinstall the original Clavia driver if you want to use the original editor again.

Windows 11: Driver Signature Enforcement

Windows 11 may block the unsigned WinUSB driver. If Zadig fails to install it, boot with signature enforcement disabled:

1. Start → Power, hold Shift and click Restart.
2. Go to Troubleshoot → Advanced options → Startup Settings → Restart.
3. Press F7 — Disable driver signature enforcement.
4. Once Windows has booted, run Zadig as Administrator and install the driver as described above.
5. Reboot normally — the driver persists across reboots.

Removing the Zadig/WinUSB Driver on Windows 11

Step 1: Uninstall the WinUSB driver

1. Connect the Nord G2 to your PC
2. Open Device Manager (Win + X → Device Manager)
3. Find the Nord G2 — it will likely appear under “Universal Serial Bus devices” or “WinUSB devices” (not as a MIDI device)
4. Right-click the device → Uninstall device
5. Check “Attempt to remove the driver for this device” (or “Delete the driver software for this device”)
6. Click Uninstall
7. Disconnect the G2

If Windows reverts to WinUSB automatically on reconnect:

• After uninstalling, also open Device Manager → View → Show hidden devices
• Look under “Ports (COM & LPT)” or “Sound, video and game controllers” for any ghost entries and uninstall those too
• Then run the Clavia installer

Tip: If the Clavia driver installer doesn’t detect the device properly, try running it as Administrator.
