I don't know if someone already said this, but i had 2 of each of the different kind of pelican joysticks...the smaller ones with no cord compartment and the larger ones with a cord compartment, both of one of the kinds, not sure which, start and back buttons did not work, and I am not sure why exactly. Mine were the universal kind. one kind my computer recognized as an "integral symbol"b, or squiggly line b, whatever, and the other it recognized as a 4 way wheel or something. Hope that helps some.
