- Ensure the 5V power adapter is correctly connected and providing power to the KVM switch.
- USB Devices (Keyboard/Mouse/Peripherals) Not Working:
- Check that the USB A to B cables are properly connected from each computer to the 'USB IN' ports on the KVM switch.
- Ensure the USB peripherals are connected to the 'USB 3.0 OUT' ports on the front panel.
- Verify that the KVM switch is receiving adequate power from the 5V adapter.
- Switching Not Functioning:
- Switching is not supported when computers are in sleep mode. Wake up the computer before attempting to switch.
- Ensure the desktop controller is securely plugged into the 'SWITCH' port on the KVM unit.
- No DisplayPort (DP) Support:
- This KVM switch is designed for HDMI interfaces only. It does not support DisplayPort devices. Avoid using DP to HDMI conversion cables as they may cause compatibility issues.
