It has a QS77 Chipset with a Intel Panther Point USB Controller (as far as I can say).
The problem was, that a connected external harddisk case (it has a JMicron USB2Sata bridge JMicron JMS539 [1]) or even a simple usb 3 memory stick, it was always connected at highspeed (usb2) instead of superspeed (usb3) (see usbconfig in [2]). Of course, the attached harddisk drives only appeared to have only 40MB/s transfer rates instead of 400MB/s.

Below 9.2-RELEASE and 10.0-RELEASE, the device will only appear as a HIGH-speed device (usb2) instead of a SUPER-speed device (usb3). (e.g. output dmesg or usbconfig) >Fix: By accident I found this commit: http://lists.freebsd.org/pipermail/svn-src-stable-9/2012-November/003213.html I then realized, that the pci dev id on my intel nuc is 0x9c318086 instead of 0x8c318086. In a fast hack I added the same code for this id in a 10.0-RELEASE Generic kernel [3] and the problem was solved [4], the devices are now correctly routed to xhci and have superspeed support. I hope this pr helps to integrate the solution to FreeBSD, but I think the patch is not finished yet (maybe you would change the descriptions etc, as my knowledge of hardware naming is limited I'm not able to do). But as it doesn't change much, I'd define it as production-ready.
