Be aware that if you are calling a subVI from multiple places in the program, it can be misleading to open the subVI and view its front panel to try and understand what is going on because you may or may not see all of the data that is flowing through the subVI. The data may move to quickly for the screen to update and display every piece of data.

For instance if the system alternately calls the GetAxis with USB1 and then with USB2, you may, or you may not see the alternating USB1 and USB2 values. Depending on the timing, you might see just one, or the other, or both at different times.

Also, since your diagram is large, it may be easier for us to diagnose your actual code than screen shots of it.
