How do I connect to the Vivado SDK FPGA serial port?

Why does /dev/ttyUSB0 disappear once I program the FPGA port using Xilinx Vivado's SDK? My FPGA program is running as expected, but I'm still trying to connect to the serial port so I can read the output.

Make sure you connect both USB cables to both the JTAG and UART connections on the FPGA board (and of course connect those cables to your computer).

You'll probably find that /dev/ttyUSB0 exists right until you program the board. You'll also probably find that /dev/ttyUSB1 persists after you program the board. That's the one you want to connect to via minicom -D /dev/ttyUSB1.
