So... It looks like this maye be solved, at leats I have not had issues for the past few hours. It looks like what helped was installing the host drivers from
http://www.frescologic.com/support.php as I have a Fresco USB3 hub in my laptop, but I'm not 100% sure.
Incidentally this would go against the advice you have on this page
http://support.displaylink.com/knowl...ncy-desktop-pi where you say
"If you have Windows 8 or above installed then the driver is supplied and controlled by Microsoft"...
