With a kernel built from sources dated 2016-05-29 at 23:57:35 UTC, when
attaching my external hard drive (near-line backup device), I get the following

Interestingly, even though this motherboard has both USB2 and USB3 ports, and
dmesg includes
uhub1 at usb1: vendor 8086 EHCI root hub, class 9/0, rev 2.00/1.00, addr 1
...
uhub2 at uhub1 port 1: vendor 8087 product 8000, class 9/0, rev 2.00/0.05, addr2
but every device I plug in, regardless of USB connector, gets attached to uhub0
(the one for xHCI)! So I cannot get the external drive to work by connecting
to a USB2 port.
Any suggestions?
To avoid the problem, please add "userconf=disable xhci*" to /boot.cfg.
The xhci driver tries to route all USB ports (even 2.0) to xhci
as possible if it's Intel PCH. (see sys/dev/pci/xhci_pci.c)
You can see some information about port routing by booting kernel -x.
