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.
Thanks for the Help @OyyoDams, for some reason the pad needed a remap but it seems that it was not the main cause of the problem.
I've run a chkdsk scan on the HDD to find that some sector might have been damaged so I've also run a repair while it was scanning.
Seems like the scan/repair have resolve the issue so if any of you have a similar problem, check your HDD or drive to make sure it's not damaged or that the files got corrupted from having it unplugged while running.
