As a note, it looks like lsusb shows both controllers by retroarch is only listing one Under Device Index.

I'm wondering if there's a way to force both to show?

@caver01 ok. I was lazy in my wording. It doesn't make me want to read it. It's obviously / hopefully the right log file.

@soonerdoc I tested sending buttons from the 360s directly and had the same results. I believe its an issue with rgbcommaner. no big deal if you don't mind errors but I do. I decided to go pc on this arcade build now. New os but new problems :). I'll checkin again but please contact me if you find a soultion.
