ERROR_DEVICE_FEATURE_NOT_SUPPORTED
The device does not support the requested feature
ERROR_DEVICE_FEATURE_NOT_SUPPORTED indicates that the command reached the device path, but the requested capability is not implemented by the hardware, firmware, driver, or transport.
Verification
- Query device capabilities before issuing the optional command.
- Compare firmware and driver versions with vendor requirements.
- Check whether virtualization or a bridge hides the feature.
- Distinguish an unsupported feature from an invalid parameter for a supported one.
Fallback
Use a documented alternative or disable the feature for this device class. Repeated retries do not add a capability that the device does not advertise.
