It also seems to be the only example of an USB virtual serial port for STM32 devices that I could find after extensive googling. It would be nice to get hold of it. Alternately I'd appreciate if someone could point me to a complete USB serial port example I can get to work on the F3 or F4 discovery with minimal effort (I know, I should learn the USB spec but you've got to start somewhere).

There is a link on this forum to a COIDE project that uses the VCP.  It is not perfect but it works and is a good place to start.  I had it working with the STM3241G_Eval board in short order.

No kidding?! This thread is pushing 4 years old before the forum last fatally crashed, the original posters are unlikely to respond. I wish we could lock threads to stop getting questions like this.
