Here are the most common troubleshooting steps.
1. Make Sure the Keyboard Is in Wired Mode
2. Try a Different Cable or USB Port
Not all USB cables support data transfer—some are charging-only cables.
Replace the cable with a known data-capable USB cable.
Try a different USB port on your computer.
Avoid USB hubs or docking stations during testing; plug directly into the computer.
If possible, test the keyboard on another computer to rule out system-related issues.
3. Check the Internal Daughterboard Connection
If your keyboard has a daughterboard, you may need to inspect the internal connections.
Steps:
- Open the keyboard case carefully.
- Check whether the ribbon cable or connector between the daughterboard and the main PCB is loose or partially disconnected.
- Inspect the port pins for bent or damaged pins.
- Reconnect the daughter board and main PCB.
