Thanks for joining the community and post this matter.
I just checked device manager on same NUC model and I have Intel(R) 7 Series /C216Chipset Family USB Enhanced host controller, they all are USB 2.0 versions
In regards to your second question, you may want to check the following NUC model: DC53427HYE
This one comes with two different USB controllers:
Intel 7 Series /C216Chipset Family USB
Intel USB 3.0 eXtensible Host Controller
Thank you for the quick response!
I wanted to know why are there TWO host controllers,. if all 5 USB ports (even the inside header) are going through one controller? The second controller isn't used at all?
My device manager looks like this: http://postimg.org/image/7sf36jjt5
From this I assume it has two completely separate usb host controllers, which each may have several ports.
So the question is: are there more USB headers on the motherboard which are on the other controller?

Thanks for the picture. That is exactly what I have on my demo computer, your NUC model has only USB 2.0 ports and it will show as your picture. Please bear in mind your NUC will come with one USB controller and again, that is called Intel 7 Series /C216Chipset Family USB.
Please see my computer picture attached.
I understand that it has only one controller type, only USB 2.0 ports, but this doesn't necessarily mean that it has only one usb controller, does it? In my desktop PC I have only USB 2.0, only one controller type, but still can attach more devices, which will be on separate controllers.
Sorry to argue again, but I do not understand this behaviour:
- I attach the device and the bandwidth for the first is: 20% system reserved, 61% device
- I check the OTHER controller, which shows: 20% system reserved.
From this it still seems, that this isn't the same controller.
It's one USB controller for seven USB 2.0 ports
See the following information:
The board supports seven USB 2.0 ports. The port arrangement is as follows:
• Three front panel ports (via one dual-port internal header and one front panel
• Two ports are implemented with vertical back panel connectors
• One port is reserved for the PCI Express Half-Mini Card
• One port is reserved for the PCI Express Full-Mini Card
All seven USB 2.0 ports are high-speed, full-speed, and low-speed capable.
Okay, understood, thank you!
