STM32 Composite Device

[arduo]

Hi there,

i am working on a composite device with STM32F4 and i got it working.

I get in the device manager a MSC device and a serial com port. The issue now is i can't open the com port with any terminal program it doesn't respond.

Anyone have experience with that?

I tried to change set and get line coding but that doesn't change it.

I will attach my project.

Thanks for everyone who helps i am struggling with this for very long

Cheers 😎

How is this project a composite device? As far as I can see, you have a compiler switch which either defines the device as CDC or MSC. I don't see how the two interfaces are running together.

the switch is just because the project is able to use cdc+msc or msc+hid or cdc+hid

Hi.

How did it go, did you find the problem ?

I am going to implement MSC+HID , and are looking for info how to do it.

So this is perfect, thank you for posting the code.
