USB Hub for One S

There's not a lot a difference between hubs in terms of functionality and quality. You just need to make sure the one you're getting is rated for USB 3.0. If you need to draw significant power from a hub, like plugging in a hard drive that's solely powered
through USB (and not with an external power adapter), then you should make sure your hub is powered (it has its own power supply).

Wait... did you say you're connecting 4 Kinect adapters? Like, connecting FOUR Kinects to your Xbox One S? I'm pretty certain that it can only handle one.

I use one from Rock Band (360) on my Xbox one (Day One edition) and it works great. I use it to plug in the usb wireless adapters for Guitar Hero. I would assume that any basic USB hub will work. 3.0 would be the route to go.

yes I use a powered USB 3 hub with mine I have my Kinect and tv tuner and external raid array running though it zero issues and have had it that way since one S came out

Yes I agree removing a USB port on the S was a bad idea, the One used to have a USB on the side which was handy but its been removed now.

Let us know which 1 you get as I might be interested in getting one.

The 3rd USB wasn't removed, it was moved to the front panel below the disc slot. USB 3.0 powered hub will work fine. I have used the same one on the 360 and the Xbox One for more than 2 years with no issues. This one from Amazon works great http://tinyurl.com/gpxhqkv
It can be used without the 5 volt adapter but I use it to ensure each port has enough power.

i use a powered USB 3.0 hub on my One S my Kinect and my USB tv tuner run through it. I believe i was the first to do this as my post about doing was a long time back in the preview forums and i have had no issues with it.
