It is recommended to only adjust the lighting effect and brightness, and lower the brightness under the white light, otherwise the keyboard will not work due to insufficient power supply of the computer interface. It may be improved if it is plugged into an interface above USB3.0 port. DisclaimerAll accessories need to be self-assembled, and there are no additional accessories in the future.
