I see a number of functions to open the ftdi interface based on various things. How would I go about opening the ftdi interface based on a user input string such as “/dev/ttyUSB0” or similar alias? I only need to do this on Linux, specifically Ubuntu.
If I can’t do this directly through the ftdi interface, what is the easiest way to use other tools to convert “/dev/ttyUSB0” into “0403:6001” through code?
Thanks,

If it's available on your system I would actually recommend /dev/serial/by-id:
$ tree /dev/serial/by-id/
