I’m facing the same kind of issue. ES actually sees that my controllers are connected but when entering the Controller and Bluetooth Settings to map the controllers none of my connected controllers work. ES just don’t see any input at all.
I have 8bitdo SN30 Pro controller paired with 8bitdo wireless receiver and also 2 old school DB9 joysticks from C64/Atari St era connected via USB by Jakadapter (Stelladapter compatible). Also I have old wireless keyboard that seems to be working always no matter what.
If I connect 8bitdo controller alone I can then map controller just fine. Same thing happens when I connect the dual DB9 Jakadapter via USB, I can then map both of my DB9 joysticks just fine (excluding the A button skipping which is not possible for some reason).
This worked just fine last night running V33, tonight when I woke the system from sleep none of my controllers worked anymore. Same situation remains after reboot also.
