Since upgrading my version of OSX, my computer no longer detects a USB game controller. I know the controller is in working order because my Linux machine can talk to it. I don't know which version broke it, but I have photo evidence of the controller working about a year ago and I'm currently running 10.11.3 (Mid 2014 MBP). I can't divine anything useful out of
/Applications/Utilities/System Information, maybe you can.
How do I debug the onset of incompatibility with my USB game controller?
