Pi shuts down when connecting an NES controller
-
I have a GPIO adapter v1.2 connected to a Pi3, I have wired NES controller sockets via this method PetRockBlog GPIO adapter. Occasionally, when connecting a controller, the Pi will start to shutdown. This has happened with different NES controllers, NES advantage controllers, and SNES controllers (via a custom SNES to NES adapter)...
Anyone know where I can start to troubleshoot this? Is there a log I can check to determine the cause of the shutdown (kernel panic or some sort of failsafe engaged)? Could this be a voltage spike causing the Pi to shutdown?
Looking for ideas as to where to begin... :/

As described at https://github.com/petrockblog/SNESDev-RPi#button-polling a shutdown command is issued when the button on the GPIO adapter is pressed five times. Maybe that signal is somehow inserted into the RPi when you connect your controller(s).
Thedmesgcommand might give you some more insights into what the shutdown is causing.
