Quoted from Chosen_S:I have to disagree. The LEDs pull more amps than we realize. The resistors at the power supply at the USB plugs get too warm from the draw from the LEDs. It is not wise to put LED strips pulling 5V from any USB port on any pc.
The only thing that the service USB ports should be used for is updating code in my opinion
If that's the case PB should state that that's all they should be used for.
