Open Joystick not consistent IDs

Hello, we are trying to run two instances of SDL for a robotics project. One instance of SDL to control robot 1 and another instance to control robot 2 through separate joysticks. We are plugging in two Microsoft XBox 360 controllers to the same laptop running Mac OS X 10.10.5.

The problem is:

Code:
    // Open SDL connection with the joystick                                                                   
    m_joy = SDL_JoystickOpen(m_joystickID);


Is not consistent with separate instances of SDL. For example.

We assign Instance 1 to open id 0 and Instance 2 to open id 1. Most of the time they end up both mapping to the same controller and only some of the time do they go to different controllers. As a sanity check we tried assigning both opens to joystick 0 yet still same behavior.

The GUIDs return exact duplicates.

Does anyone have suggestions or fixes?

Thanks!
