Hi, johannesdkFirst, you should buy active USB 3.0 controller. For example KTU3FR-4P. Next, don't install microsoft's or fresco's drivers included with card - they are faulty. Working drivers you can donwload by Driver Easy Free application. I was delving into logs for couple days and almost sent my HMD on RMA, buy I noted that drivers of my USB PCI-e card wasn't correctly loaded.My problem was solved thanks to Oculus Support, Driver Easy Free and my inquisitiveness.
