I've updated recalbox to 9.1, hoping the update would fix this, it didn't. BUT what I actually think the issue is, is my game controller apparently needs a bluetooth dongle to plug in to the raspberry pi USB port. I found that info on the recalbox website. So I guess instead of relying on the raspberry pi bluetooth connection, it will use the dingle connection instead?
Won't those two bluetooth resources conflict with eachother?
