Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Adapter not recognized by device. | Loose connection; Incompatible device; iOS version issue. | Ensure the adapter is fully inserted into both devices. Verify your external device is compatible with iOS OTG. Update your iOS to the latest version. |
| Slow data transfer speed. | External device limitation; File size. | The adapter supports up to 480Mbps. Ensure your external device is not the bottleneck. Transferring many small files can be slower than one large file. |
| External device not powered. | High power consumption of external device. | Some external devices (e.g., portable hard drives) require more power than an iOS device can provide via OTG. Use self-powered devices or a powered USB hub if necessary. |
