I was following this thread on and off for a while then finally saw the success that was had with the Kinect v2 for Windows hub. I ordered one from Microsoft on Friday and it arrived Monday afternoon. I also ordered a 25' Tripp-Lite USB 3.0 cable but that won't arrive until Wednesday.
The Kinect for Windows hub comes with a 6' USB 3.0 cable which, as it turns out, is actually enough (now 15') to let me reach my TV from my media cabinet. I'll have to put the Kinect away after each use, but I think I may prefer that to running the cable behind the TV and leaving the Kinect front and center all the time. I'll see how I feel once my 25' cable arrives.
The important thing is that hub indeed works to extend the Kinect. Plugged the hub into the XBox One's USB port and it was business as usual. I don't use the IR functionality, so I can't comment on that, but I think its understood now that you need to take some additional measures to get it working again using this extension method. I can't honestly say I use the Kinect much, but at least I can now have my XBox One neatly stored in my media cabinet and still be able to use the Kinect if I want to.
