Code 41: Windows loaded the driver but cannot find the hardware device

The driver exists but Windows cannot find the expected hardware.

First action

Confirm the device is actually connected/present, then reinstall/redetect it.

Use the error code as a Windows device-state clue. It does not by itself identify the exact failed component inside the hardware.

Then verify

Do not stop at the code disappearing

  1. 1

    Check cable/port/power for external devices.

  2. 2

    Use official hardware diagnostics if Windows still cannot find it.

After Windows reports the device normally, run the matching DeviceOK test when one exists—for example camera, microphone, keyboard, mouse, controller or audio—to confirm the user-facing function works.
