looks like everything is working, I plug the usb and the FTDI creates the VCP correctly then I download a firmware to blink the led and the led blinking, finally  I wrote this quick function that receive chars and search the sequence "hello" if found returns the sequence "hello world!"

I just download the firmware and click run, then I type in my computer hello and this is the answer that the square inch tracker sends to me.

I don't think I can sleep tonight, I will keep awake until I hit the keyboard with my face.
