Thanks for the info, and testing!
Today i've received my third Dell D3000 dockingstation. Now running for 3 hours on the RIGHT USB port and a clean Windows 8 installation with the lastest USB/DisplayLink drivers.
In this stage i haven't experienced any black-out...... (yet)
Working on the laptop, and extended the display via HDMI to my TV, playing videos with VLC
I think i'm getting an longer USB3.0 cable to connect to dock with the laptop. Because the length of the original cable is wayyyyyyyyy too short
Or is the provided USB3.0 cable something special??
