Although I submit these patches as the previous reply suggestion, I am stilling wondering the IOMMU with USB controller. I think the most of USB controller didn't need to create entities in IOMMU to support scatterlist. Once the hcd supports that(sg_tablesize > 0), it could support infinite scatter pages?
