I am using Ubuntu 24.04, the latest version of CHIRP, and an FTDI LTD FT232 Serial (UART) IC on Bus 001 as Device 003. My laptop identified the FTDI chip for me. But I do not have /dev/ttyUSB0 and I have tried 4 or 5 recommendations with no success. What can I do to fix this problem, as the program is useless without it.

    Please [edit] your question and add links to the "4 or 5 recommendations" you already tried to avoid getting the same recommendation here. Copy&paste the commands and output you used to find out that your laptop identified the FTDI chip. – Bodo Mar 17 '25 at 17:39
  • Look at your system startup log (watch your kernel discover the hardware) with the terminal command sudo journalctl -b 0. Could your FDTI chip be called something else? ls -l /dev/tty*. If the program requires /dev/tty0, set up an alias with udev. – waltinator Mar 17 '25 at 18:40
  • In particular, please share the vendor and product IDs - these kinds of problems are often caused by conflicting udev rules – steeldriver Mar 17 '25 at 20:09
