Thank you for the response,
I tried to bypass the linkbox(both USB, HDMI and both at the same time) and no difference, still error 108 and the red light. Unfortunately I dont understand whay you mean by "try the shorter cables and sub them for the 3-in-1". Do you mean to disconnect the 3-in-1 cable from the headsett and putting the linkbox cables directly into the headsett?
USBDeview also recognizes the headsett when I bypass the linkbox.
As for the reason I believe it might be USB or possibly power related is that when installing VIVEPort and doing the automatic setup, at the stage when it tells you to connect the linkbox it will recognize the HDMI for some seconds before loosing it again, but the USB is never recognized as connected by VIVEPort. The powerbrick for the Linkbox/HMD also stays at room temperature, while the base station powerbricks have a slight sign of temperature buildup.
