[REQ] Xilinx USB configuration (USB programmer)

[igor_d24]

I am looking at possibility to clone (for my design) Xilinx USB configuration circuit (USB programmer) which is implemented on ML-605 board (docs are downloadable from Xilinx): CY7C68013A micro-controller  + XC2C256VQ100 CPLD. It is similar to off-the-shelf USB II programmer (as far as I know the difference is in using FPGA instead of CPLD).

My understanding is that micro-controller loads firmware from PC via USB, so no f/w flashing is required that leaves only CPLD h/w to sort out. Anybody can share it? I asked Xilinx FAE-s, they didn't help. Do you know if it's possible to clone the CPLD bitstream?
