STM32F2 USB Host Virtual COM with DMA

I have a module which I need to communicate with virtual com by USB with a STM32F2.

Which means that I need to STM32F2 to be USB host and then connect to the virtual com over USB and I also need the transfer to be done over DMA.Unfortunatly I cannot find any examples where STM32F2 is USB host for Virtual com. Has anyone seen any example code for this or can help me how to achieve this?

The 2.1 USB Firmware Library has a VCP that works with the STM32F2

Can you please post  link?

When I google  for 2.1 USB Firmware Library I find:https://my.st.com/public/STe2ecommunities/mcu/Lists/cortex_mx_stm32/Flat.aspx?RootFolder=https%3a%2f%2fmy%2est%2ecom%2fpublic%2fSTe2ecommunities%2fmcu%2fLists%2fcortex_mx_stm32%2fSTM32%20Legacy%20Firmware%20Libraries&FolderCTID=0x01200200770978C69A1141439FE559EB459D7580009C4E14902C3CDE46A77F0FFD0650...And on the  OTG examples there is no example where stm32 is USB host for VCP (only when stm32 is device for VCP)
