I see that usr0 has an entry called “invert”:
/sys/devices/platform/leds/leds/beaglebone:green:usr0/invert
It works as expected, which is nice. But I also noticed the “invert” functionality doesn’t exist for usr1, usr2, or usr3.
Is that intentional, or is there something missing from usr1, usr2, and usr3?
