This the newer, supposedly functional, ft232... Unplugging and replugging put on the console ugen1.4: <FTDI FT232R USB UART> at usbus1 (disconnected) uftdi0: at uhub1, port 3, addr 4 (disconnected) uftdi0: detached ugen1.4: <FTDI FT232R USB UART> at usbus1 uftdi0 on uhub1 uftdi0: <FT232R USB UART> on usbus1 But it still can't connect to the serial port of the correspondent host, which is up and running. Meanwhile, the FT232 which appeared faulty is working fine overnight on RaspiOS Buster. Thanks for reading, and any suggestions.... bob prohaska
