Default 1.0.335 driver stops working on 4.5.6 Kernel

It was working on 4.4.9 kernel.
BTW Running Fedora 23


dmesg yields:

Hi eggestad,

I see your evdi kernel module is 1.1.65 while you mention SW version 1.0.335. Could you please make sure kernel module and user mode daemon and libevdi.so versions are in sync? All should be 1.1.x.

Default Version check

Took a while before I could check version.
Carefully removed all traces I could find of 1.0.* things.
/usr/libexec/displaylink/DisplayLinkManager
is the 1.1.65 version.

On both 4.5.7 abd 4.4.9 kernels the only thing in dmesg is :

It just seem to me that this version of the displaylink driver refuses to recognize the MB168+ display
