Feel like the overpriced PC adapter really killed off what could have been a thriving scene for the second Kinect. Amazing piece of tech for its time.
If you have a semi decent soldering iron it's very easy to make a DIY pc adapter btw. The 36w power requirement is very easily managed now with most GaN chargers too (12v3a).
I chased a Kinect v2 for PC, but the driver story on linux isn't great (since it never hit that broad distribution). Well, that was a few years ago, it may have improved since then.
