According to schematic, there is no such LED controled by USB, there is a red LED, but it is connected as PWR-LED on PL4.

 

To turn it off :

echo "none" > /sys/class/leds/orangepi\:red\:power/trigger
echo 0 > /sys/class/leds/orangepi\:red\:power/brightness

There are 3 LEDs, according to my OPi3

Specification: http://www.orangepi.org/Orange Pi 3/

"LED: Power LED, Status LED and USB3.0 LED"

 

In /sys tree there are two controls only (for red power and green status)

I have turn off red power (dont like this intensive color in dark) and green set as USB activity signaling. But can't turn off red USB LED.

I don't find such USB LED on the schematic ...

Can you provide a picture which can shows it's location ?

BTW, with Armbian Mainline image, I'm able to toggle both STATUS and POWER with a script using command I've mentioned ...

My OPi3, red USB LED is lightning only:

According to schematic, this one is effectively attached to USB3 hub on the PLED/FN_C pin.

But I don't think it can be controled via kernel. Only way to get rid of it would be to break it ...
