Controller rebooting at random

Im recently having a problem where my controller re boots when I use it.
I can Launch Live, and Live sees the controller as a controller, and the LED status is correct, but then when I press a button on the controller, the controller will reboot. This seems to have happened since I updated to the latest version of Live 11.1.6, but not totally sure.
I have tried different USB cables, connecting through a hub and connecting to Trash can mac directly, all the same issue. Any ideas?
thank you!!

Actually I think this was user error… some kind of IAC bus midi feedback loop was causing the controller to crash and reboot. I turned off the IAC bus and the problem went away. Not totally sure how it was getting back to the controller, but … moving on!
thank you!
