Your are being a bit vague.
1) Does the stick show up in the "Map Controllers" panel in the drop down list?
If it does, do any commands show up mapped to the various inputs in the "Mode 1 Function" column?
Please give a detailed description of what the "Map Controllers" panel looks like, a picture would be even better.
The game will support and work with any USB connected joystick. If you loaded some type of controller software, then remove it first and try using the stick without that software installed. The game has a native understanding of joysticks and does not need any controller software installed.
See the picture here to get an idea of what a properly mapped joystick looks like in the "Map Controllers" panel.
