XP10s wont activate PITCH slider with USB plugged in

The title basically says it all im STILL trying to use DeckaDance and my two XP10s for two years now with no luck. Finally i am able to get the sound into the right locations but i have another problem now. If the XP10 is unplugged from the USB on the left.... i can move the pitch slider with my mouse if i leave it plugged in, it DOESNT move at all If i unplug both XP10s then i can move both Pitch sliders on Decka with my mouse no matter what i do i can not get deckadance to move its pitch slider if i use the pitch sliders on the xp10s themselves This is two years now and i still cant get this going
