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.
