Well in one of those acceptable but frustrating moments, I was able to get the controller to correctly output readings. This was achieved after unplugging and plugging everything back in and uploading the tutorial code again. I also swapped the Bot Board II with another just for good measure but the previous board hadn't been giving me any issues until the PS2 controller problem. Of course I could swear that the code is identical to what I've been using all along and I don't think I made any different connections than before.
So I'm glad it all works but frustrated that I didn't learn why I was having problems to begin with. If I happen to find out I'll be sure to share it with the group. Here is the code that successfully worked.
Code:

for index = 1 to 18 ; temp(0) contains a dummy variable so we don't send it to the PC
; sending all the data to the PC
serout S_OUT,i57600,[" ", dec3 temp(index)\3] ; Basic Micro Pro IDE <= 08.0.1.7

goto main
If anyone's curious, I'll be using this PS2 controller for a
mecanum wheel robot. The math behind getting it to work is a little complicated but I'll post some project updates and sample code once I get it working.
