Reverse-Engineering DisplayLink devices

USB to DVI for Hackers

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.
