I'm not at all sure what you're asking here.
Are you looking to use USB to communicate with the Chipscope cores? The Chipscope cores are connected to the internal JTAG bus and there is no support for using USB to communicate with the cores.
You have to connect to the JTAG port of the FPGA to a Xilinx JTAG pod (a USB-II pod if you want to connect it to a modern computer as opposed to a Parallel Port IV cable). The Xilinx pod requires a driver, which is normally installed when you install the ISE/Vivado software suite (unless you declined the driver installation).
