Quartus Prime Lite 20.1 cannot recognize DE1-SoC board via USB cable - Quartus Prime Lite 20.1 cannot recognize DE1-SoC board via USB cable I run Quartus Prime 20.1 Lite from Ubuntu 20.04 LTS and tried to program DE1-SoC board, but Quartus cannot recognize the board. "Hardware Setup..." shows "No Hardware" while the board is hooked via USB cable. Do I miss any settings? Thanks!
