USB Serial with STM324x9I-EVAL

I am trying to interface a pair of XBees with a pair of STM324x9I-EVAL boards to open up a wireless communication link. I'm considering using the microUSB breakout board to interface with the dev. board but am unsure what is required to properly interface on the micro-controller's end. I know that the breakout board uses the FTDI FT231X USB-to-serial converter and that the typical way this is used is to install the FTDI driver on the host device, recognize it as a VCP, and send data over the link serially. I'm wondering what's the best way to get the XBee communicating with these dev. boards. Is it possible to somehow get the FTDI driver to install on the micro and, if so, is it worth it? Or should I scratch the VCP driver and attempt to communicate directly using USB and, if so, is this difficult to program? I'm considering scratching the USB interface if it's too difficult and using the board's RS-232 if it proves to be too difficult/time-consuming.

Any information is helpful at this point. I will admit I have little experience with the STM32 micro-controllers and with communications interfaces/protocols so please be kind...
