interesting idea... and worth a try.  thanks!

[Controllers Recognized by LB and BB, but not registering inputs]

Hi all, building a custom cocktail arcade with Windows 10 and LB/BB using 2 bog-standard 0-latency USB encoders from Amazon.  Windows sees them and they work fine, Emulators see them and they work fine.  LB/BB however sees them (they are shown under tools>options>controllers), but allows me limited interaction with them (LB- no inputs work, BB- joystick works but no buttons).  Of course I've tried to reset the mappings and nothing gets recognized. I've tried every iteration of using 1 or both controllers ("Enable Game Controller"), I've clean installed, I've deleted LaunchBox\Data\InputBindings.xml

No luck.  Any paths I have not explored yet?
