Hosting a USB -> RS232 on STM32

Hi

I have a project where I need to host a CDC on an STM32F microcontroller.
The usarts are in use hence the need for the CDC.

I have found library code from STs cube in
"stm32cubef4\STM32Cube_FW_F4_V1.7.0\Middlewares\ST\STM32_USB_Host_Library\Class\CDC"
which configures the USB to host a CDC. The problem I have is making my application talk to the device.
Obviously when a USB to serial adapter is connected to a windows PC, a COMx
interface is created which can then be connected to by an application.
What I'm not clear on is how I would make the firmware in my STM32 talk to
the CDC so that serial data can be passed to a connected serial device.
I have spent a lot of time searching for examples on this issue, but have not found any.

Can someone give me some hints on how to connect to the CDC device
please?

Thanks

Andrew
