8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device not recognized or intermittent connection | Insufficient power to the connected device; loose connection; driver issue. | Ensure all connections are secure. Connect an optional 5V power adapter to the cable's power port. Try connecting the device directly to the computer to rule out device or driver issues. Try a different USB port on the host device. |
| Slow data transfer speed | Connected to a USB 2.0 port; device is USB 2.0; host port issue. | Ensure both the host port and the connected device are USB 3.0 compatible. Connect the cable to a known working USB 3.0 port. |
| Cable does not work | Faulty cable; incompatible device. | Test the cable with another known working USB device and host. If the issue persists, contact customer support. |
