WINBIO_E_UNSUPPORTED_DATA_FORMAT
WINBIO_E_UNSUPPORTED_DATA_FORMAT means the requested sample or template data format is not supported by the sensor driver. The caller and the biometric unit do not agree on the representation of biometric data.
What to check
- Use the formats reported by the sensor and engine adapters instead of hard-coding a format from another device.
- Check that the correct vendor driver is installed after a device replacement or driver update.
- For raw capture, confirm that the selected access mode and data format are supported together.
