Arturia wanted to cater to the Linux audience by slapping "Linux compatible" on their USB Class Compliant device, but they forgot that they would have to release some way to interact with the controls of the device from Linux (eg. port the AudioFuse Control Center to Linux). Honestly, a simple API would have been sufficient, because Linux people come up with their own solutions, that's how we roll. But instead they just removed the "Linux compatible" stamp after we went and bought the device.
