STM32F4 USB SERIAL

Working on STM32F4 Discovery and using CubeMx to generate basic structure for the program.

I am connecting FT232 based USB TTL Module to the USB OTG port of Discovery using Micro USB to Female OTG Cable.

I am using CDC example VCP, When I connect to PC with Discovery, it behaves as VCP and I can see it in device manager, But I want to behave it as normal USB and connect external Serial module.

Is it Possible?

Not without a lot of software/knowledge on your part to effect the connectivity between the two USB ports.

Sorry I am unable to understand. What exactly you are saying? Instead of answering my question, you are giving vague answers. I didn't expect this from you Clive. We come to this community to seek some knowledge and for getting answer to our question. Kindly provide proper answer to the question.

you would need to learn how to use the mpsee on the ft232 first then port that code over to your project

If you expect me to perform your job function, or carry you up your own learning curve, then you're going to leave disappointed.

If correctly interpreted, my answer is to go figure out how the USB protocol actually works, and why there is a disconnect between what you seem to want to happen, and the mechanics of making it happen.

What you want to do is complicated, while I think it is possible, it doesn't mean that I want to spend hours of my time demonstrating/explaining that.

What does 'Normal USB' mean? You want the STM32 to act as a HUB?
