Cause: Windows Power Management hibernated the USB port.
Solution:
During registration, the software performs a "quality check." secugen device registration
Allow users to register SecuGen fingerprint scanners to their accounts so apps can capture and authenticate fingerprints securely and reliably.
| Cause | Solution |
|-------|----------|
| Loose USB connection | Use a powered USB hub; avoid front-panel ports. |
| Corrupted driver cache | Run pnputil /delete-driver *secugen* /uninstall, then reboot and reinstall. |
| Conflict with other biometric software (e.g., DigitalPersona) | Uninstall competing fingerprint software; SecuGen drivers use exclusive handle to the sensor. | Cause: Windows Power Management hibernated the USB port
If you are an integrator using the SecuGen SDK (C#, C++, or VB.NET), device registration is handled via code. The typical sequence is:
// Pseudo-code example using SecuGen SDK
SecuGen.FingerprintSensor sensor = new SecuGen.FingerprintSensor();
sensor.OpenDevice(0); // 0 = device index
sensor.SetTemplateFormat(TemplateFormat.SG400);
// Registration successful if no exception is thrown
For end users using a third-party product (e.g., BioStar, ZK, or a custom HR system), look for a Device Manager or Hardware Setup tab. You will likely see a button labeled "Register Device" or "Add Scanner". Clicking this will prompt you to place a finger on the reader to confirm the handshake.
