  • I have spent hours on the internet trying to find a working driver. The broken links to ST's site don't help either (the site was redesigned recently according to a ST local field engineer I phoned).
    I eventually found the solution to be quite simple (as these usually are once you know the solution ;-).

    Simply install the simplemac software from ST. It installs the required device driver without you even knowing it. What a relief!
