FT232 - no ttyUSB* device will be created after plugin

by Olupo   Last Updated July 12, 2019 09:02 AM - source

I'm using Ubuntu 16.04 LTS. When I connect the PC with the FT232R on a DE10 Standard, the system recognizes the FT232R. But in the /dev directory is no ttyUSB* file created after plugin, not even a new tty* file was created.

I want to communicate via serial console between the PC and the FT232R. What do I have to do to make this work?
