switch (deviceInfo.DeviceStatus)

Here’s a general guide to interpreting messages, commonly seen in SDKs, demo applications, or custom integrations (e.g., with Hamster Plus, Hamster Pro, or U.are.U devices). Common SecuGen Device Statuses & Meanings | Status Code / Message | Meaning | |-------------------------------------|-------------------------------------------------------------------------| | SG_DEVICE_STATUS_READY | Device is connected, initialized, and ready to capture fingerprints. | | SG_DEVICE_STATUS_BUSY | Device is currently in use (e.g., capturing, verifying, or enrolling). | | SG_DEVICE_STATUS_NOT_CONNECTED | No device detected on USB. Check cable, drivers, or reinsert device. | | SG_DEVICE_STATUS_NEED_INIT | Device present but not initialized. Call initialization function first. | | SG_DEVICE_STATUS_FAILURE | General hardware or communication error. Try resetting or replugging. | | SG_DEVICE_STATUS_NO_PAPER / NO_FINGER | Sensor ready but no finger placed. | | SG_DEVICE_STATUS_CAPTURE_TIMEOUT | Finger was not placed in time (timeout setting exceeded). | | SG_DEVICE_STATUS_BAD_FINGER | Finger placed but quality too low for processing (wet/dry/scarred). | | SG_DEVICE_STATUS_USB_TRANSFER_ERROR | Data read/write failure – try different USB port or reinstall driver. | How to Check Device Status (Code Example – C# / .NET) Using SecuGen SDK (e.g., SGFingerprintManager ):

SGFingerprintManager fpManager = new SGFingerprintManager(); // Get device status SGDeviceInfoParam deviceInfo = new SGDeviceInfoParam(); int status = fpManager.GetDeviceInfo(deviceInfo);

case SG_DEVICE_STATUS_READY: Console.WriteLine("Device ready"); break; case SG_DEVICE_STATUS_NOT_CONNECTED: Console.WriteLine("No device connected"); break; // handle other cases...

if (status == (int)SGResultCode.SG_SUCCESS)
