This requires the STM VCP driver to be installed in order for the VCP to be recognised. The STM32 VCP driver can be downloaded here --> http://www.st.com/web/en/catalog/tools/PF257938 NOTE: Once you download and run the installation it has not installed the driver, merely unpacked the choice of drivers.
