Font left and Front right confusion

Hey, im new to the forums, but it seems like you guys can help me. I bought a new 3.5" media reader(http://www.xoxide.com/sunbeam-superior-panel-35s.html) and i have it all hooked up, but it seems that my front right and front left channels are mixed. I have 5.1 headset, and an x-fi titanium soundcard. The way that the unit hooks up to your sound is a bit weird, it doesnt go from your motherboard F_AUDIO connection, it just has 2 3.5mm jacks. They hook up to a 6 pin(3x2) connection that hooks up to the unit. Is this most likely a faulty wire or hooked up wrong, the jack that hooks up to the back of the device has a clearly writen UP logo on the top. Bad wiring? you tell me,

thanks
