So my motherboard includes 4 USB 3.0 ports however, after checking the device manager there is nothing that is listed as being Intel or Renesas USB 3.0 eXtensible Host Controller.

I specifically need an eXtensible host controller in order to successfully run a specific USB 3.0 video capture device that i own - and was wondering if these devices will do the trick. I have one PCIe 1x device and one PCIe 2.0 slots available on the motherboard.

List of items

Item I will probably purchase for testing

The product description for most of them lists as "- USB 3.0 complies with Intel eXtensible Host Controller Interface (xHCI)"
Does this mean they are capable of accepting eXtensible Host Controllers?

Also, from what you guys have noticed and from what i am assuming, they are only compliant with PCIe 2.0 slots, and not the other individual PCIe 1x slot, yes?
