Reverse-Engineering DisplayLink devices (26c3)

DisplayLink produces nice, useful USB graphics adapters. Unfortunately, they had no real Linux support. In this talk, we'll describe how we first reverse-engineered the encryption and basic protocol, prompting DisplayLink to actually release a Linux driver on their own. However, their driver still doesn't support compression. In the second part, we'll therefore describe how we reverse-engineered the compression algorithm. about this event: http://events.ccc.de/congress/2009/Fahrplan/events/3353.en.html
