The thing is that on this site
http://goo.gl/LdPES DisplayLink states that the driver is not supported for my intel atom clover trail cpu and the earlier mentioned gpu and after driver version 7.0 installation on these devices is disabled.
However when I download the latest version 7.1 M1 I can without any problem install the driver and the debug software says that everything is in perfect oder.
Even though the system seems to be i perfect order, I still don't have any picture on my external display...
