Double check that it is all correct. Your computer can communicate with the AudioMoth via USB HID but not USB Serial. This is normally because the TTY rule in 99-audiomoth.rules has a typo, or because your default user is not a member of dialout and thus cannot write to the serial port. Check that both are correct, logout and login again, and disconnect and reconnect the AudioMoth, and it should start working correctly.
