There is a USB detection. When the USB is detected, the red light in RGB will be displayed. When the key is pressed for the first time, it will light up white. There are five gears corresponding to five colors, but the light of the USB detection will always affect the color of the gear. How to solve this problem?

Then make the red light alone. If you make it together with RGB, the colors will be mixed.

If you don't need to pay too much attention to the charging status, you can remove the red light

The USB power indicator is set up separately.

I don't quite understand what this means. Where is the white light? Where are the five gears?

Two LEDs should not be used with a current limiting resistor, because turning one on will reduce the brightness of the other.

Yes, each light still uses a resistor. You can consider using a resistor array. Good soldering point.
