I have a Zero Delay USB controller that looks like the other ones I can find online, except mine has two extra red connectors. One is labeled "d3" and the other "d1".
I did some research but couldn't find any other information about them. Does anyone have any idea what they are for?
My only guess is that they are related to the indicator LEDs, but those are labeled "D1" for green (mode) and "D2" for red (power).
Thanks for any help!
