I'm trying to finish a PiMAME cabinet build using a MiniPac keyboard encoder made by Ultimarc to hook up the joysticks and buttons. It is not working when plugged into the Pi directly or via a powered USB hub. If I am reading the post right as it scrolls by on boot, then it says "device not accepting address 9, error -32". Can anybody tell me what this is and how I might fix it?
So, I'm an idiot. After calling a friend, we figured out that I had wired every single switch to normally open instead of normally closed. After fixing all of those, everything now works fine.
ugh, that stinks. I'm glad you figured it out. I did that once when I was building a PC. couldn't figure out why it would turn on for 5 seconds that shut off.
