Yes USB 5V to RAW, I didnt think about it beeing the cause, because the microcontroller was powered and could be programmed.
Ive got everything glued and working now, so I dont bother changing it again. Its also more modular now as the USB cable can be removed.
I actually wanted to circumvent the USB connector resistance because I will be pulling quite a bit of current with the LEDs, but it still works the way it is now even with only 5V 1A USB connection. The board does only get a bit warm.
Next time I will post a diagram of my project right away
