Yes, SFC30 and SN30Pro+ are both bluetooth-controllers, but i use them wired. That works fine with recalbox.
Sorry for not mention my connection-type, of course this is important information.
I did a factory reset, but that didn't change anything, the problem still exists.
Yes, it's USB3, and i don't have any USB2-Port in this computer. I actually also have no USB2-Hub here to do some testing.
Greetings
