10 fans on two controllers. Recently the software only detects 1 of the controllers. Unplugging the power from the controller and plugging it back in the software will most of the times detect it again and run. However if you touch any setting of the second controller on the software it drops it. So I figured mayb the controller is bad. So I swapped it out with a different one that was un used.. Same problem. Tried to change the controller numbers, reinstall, daisy chain cable, Y cable nothing is working.
