Hi,
I am using a rpi3 setup with Lakka. I have two PS3 Rock Candy Wireless USB controllers plugged in to the Pi. They register with the system and map correctly with no problem and if I have one controller on at a time there is no issue at all. However, it seems that if both controllers are on for multiplayer use then there is constant drop out. Basically, both controllers will randomly drop the connection and reconnect resulting in loss of control for a few seconds. I have searched this problem several times but have not found anyone having a similar problem. Is anyone aware of this being an issue and if so is there a fix or an explanation?
