First-time setup

Connection order (very important):

  1. Connect the right-side cable of the box to your PC.

  2. Then connect the left-side cable.

  3. Finally, plug your mouse into RainbowHand.

Please follow the order “right → left → mouse” to avoid detection issues.

Mouse compatibility

Most major-brand gaming mice work without problems.
If your mouse does not move after setup, please follow the troubleshooting steps below.

Troubleshooting

Q1. My mouse doesn’t move after I plug it in.

  • Check that you are using a working USB 3.0 (or normal) port on your PC.

  • Make sure all cables are firmly connected and not in the wrong port.

  • After everything is connected correctly, wait about 1 minute for the device to be recognized.

Q2. It still doesn’t work.

  • Look at the LED indicator on the box:

    • Red light: device is working normally.

    • White blinking light: no firmware or firmware error.

  • If the light is white and blinking, please re-flash the firmware according to the manual or contact support.

  • If there is no light at all, reconnect the cables or try another USB port.

Q3. Is my mouse incompatible?

Only consider mouse compatibility after you have confirmed that:

  • The connection order is correct (right → left → mouse).

  • The indicator shows a normal working state (for example, solid red instead of white blinking).

  • You have tried different USB ports or restarted the PC.

If it still doesn’t work, please contact our customer support with your mouse model so we can help check compatibility.
