apport information
** Tags added: apport-collected xenial
** Description changed:
With 16.04 and an AsRock Fatal1ty Z170 motherboard, I cannot seem to
connect USB3 devices to USB3 ports. They work if I plug them into a USB2
port. Also, USB2 devices work if plugged into a USB3 port.
I have read other descriptions of similar phenomena, but typically, USB3
does not work initially, but it is fixed by enabling the IOMMU setting
in the BIOS. Unless I'm missing it, I don't seem to have such a setting.
I do have "xhci handoff", and I have enabled that.
Excerpt from `lspci -k`:

Subsystem: ASRock Incorporation Sunrise Point-H USB 3.0 xHCI Controller

...and `dmesg | grep -e DMAR -e IOMMU`

I have also tried adding `iommu=soft` or `iommu=pt` to my kernel command
parameters, and this has not fixed the issue.
I have asked a question about this matter on AskUbuntu, but after two
weeks, there has been no activity.
