Targus 3.0 USB SuperSpeed Driver problem

[burkm]

A new problem came up yesterday after i updated to the latest version of the Intel 4000 graphics driver from the Intel download side, after the device driver Utility from Intel suggested an update to the latest driver version. After that the USB 3.0 docking station no longer was recognized but was listed in the device manager as an "unknown USB device". Un- and reinstalling the latest DisplayLink driver V7.0M0 did not work this time.
All in all this seems to be a very unstable configuration situation, because every small change in the driver environment renders the device practically useless.
I had to get to great length to have it up and running at all from the start (took me almost a whole week) and every upcoming change or driver update revives that same situation again...
