We need software written that implements a STM32F407 host mode USB driver, able to connect and communicate with USB serial devices that expose multiple virtual devices such as GSM/GPRS modems or Telit.

I wanted to get the drivers and library to use the STM32F chip as a host and connect to the Telit USB Modem.

* Implemented using this GCC toolchain 

* Using the standard STM32 USB base USB libraries

* Thread safe, implemented under FreeRTOS reference sample application

* Each discovered bi-directional stream presented as a stream from the library

Has someone done this before? If so can you help.
