Xantech 284m with Usb Uirt

I just got a xantech 284m which I have read works with the usbuirt. Problem is, when I plug it in the IR reciever on the uirt stops working.
Is this normal? Is there anything I can do to have these blasters and use the IR input on the uirt.. i dont care about the blasting ability of the uirt.
Thanks,
