Thanks George....
I did send an email.... and after much more searching... I discovered the CMU FTC support site which is really good, and has it's own forum:

However, I eventually figured out the problem the hard way... trial and error.
The caveat is that this might JUST be a problem on my PC.....
Ultimately I found that the FTC Controller program ran fine if I had the LT Game Controllers plugged directly into my PC's built-in USB connectors. Once I discovered this, I found several other combinations that did not work...
Interesting to note is that my PC has USB 1.1 ports onboard.
I also have a 4-port USB 2 card in my PC, and if I plugged the game controllers into this, the program failed.
I also have an external 4-port USB 2 hub on my desk, and if plug the game controllers into this device, the program doesn't run, regardeless of whether I have the hub plugged into the PC's USB 1 or 2 ports.
Interesting to note is that the PC was happy to recognize the game controllers on ANY of the ports, but not the FTC Controller program....
It's clear when I run the controller program that it just doesn't see the game controllers in any other location than the root USB node.... My only conclusion is that the Labview USB interface code is taking some shortcuts.....
Phil.
