Adam Caudill and Brandon Wilson gave this presentation at the recent Derbycon 2014 conference in Louisville, KY, covering their hack of the Phison 2251-03 USB controller firmware to add new “features” and functionality. They focus on the Patriot Supersonic Xpress 8GB USB drive allowing it to be repurposed for non-standard uses.
Adam has posted his code on GitHub. Slides from this presentation are available on SlideShare.
