Description:
I bought a Intel Nuc D34010WYK [0]. 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.

faked output out of my head, if you need an exactly output I will provide after
a reboot from a 10.0-RELEASE memory stick:
[root@x ~]# usbconfig
ugen0.1: XHCI root HUB 0x8086 at usbus0, cfg=0 md=HOST spd=SUPER (5.0Gbps)
pwr=SAVE (0mA)
ugen1.1: EHCI root HUB Intel at usbus1, cfg=0 md=HOST spd=HIGH (480Mbps)
pwr=SAVE (0mA)
ugen1.2: product 0x8000 vendor 0x8087 at usbus1, cfg=0 md=HOST spd=HIGH
(480Mbps) pwr=SAVE (0mA)
ugen0.6: USB to ATAATAPI Bridge JMicron at usbus0, cfg=0 md=HOST spd=HIGH
(480Mbps) pwr=ON (8mA)# - PROBLEM
ugen0.7: USB to ATAATAPI Bridge JMicron at usbus0, cfg=0 md=HOST spd=HIGH
(480Mbps) pwr=ON (8mA)# - PROBLEM
How-To-Repeat:
Attach any USB 3 mass storage (maybe any device) to a Intel Nuc D34010WYK.
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.
