I thought the later generations, especially the ones with USB3 support,
used a propretary encryption between the host and the adapter that was
not currently supported by any F/OSS operating system?  

If you look on the DisplayLink forums there are angry threads about
the lack of Linux support for the later generation dongles.



(there's a much longer thread somewhere which is more angry, but I've lost
 the link)
