| Symptom | Likely Cause | Solution | |---------|--------------|----------| | No device detected | Driver not installed | Install USB-to-serial drivers (CP2102/PL2303). | | Slow transfer (<115 kbps) | Forced fallback to SIR mode | Check FIR compatibility in software. Set baud explicitly to 4 Mbps. | | Intermittent connection | Angle too wide or distance too long | Reduce distance to 10-15 cm. Align within ±10°. | | Fails after Windows update | Driver signature enforcement | Reinstall legacy driver in test mode or use IrCOMM2k. | | Dongle gets hot | High power draw or faulty transceiver | Disconnect immediately; unit may be counterfeit/low quality. |
