Important notice on TE0790-xx variants:
Do not access the FT2232H EEPROM using FTDI programming tools, doing so will erase normally invisible
user EEPROM content and invalidate stored Xilinx JTAG license. Without this license the on-board JTAG
will not be accessible any more with any Xilinx tools. Software tools from FTDI website do not warn or ask
for confirmation before erasing user EEPROM content.
