The Digilent JTag uses FT2232, but its configuration EEPROM contains secrete data needed to be recoginzed by Xilinx ISE/Vivado. The following method only works on linux (tested on Ubuntu16.04), but the patched FT2232 doggle also works on Windows.

1. Install softwares: sudo apt-get install libftdi1 ftdi-eeprom
2. Create a file "flash_digilent.conf" with the following content:
