Right after xHCI starts: xhci-hcd xhci-hcd.1.auto: Host supports USB 3.0 SuperSpeed xhci-hcd xhci-hcd.1.auto: WARNING: Host System Error ... xhci-hcd xhci-hcd.1.auto: xHCI host controller not responding, assume dead xhci-hcd xhci-hcd.1.auto: HC died; cleaning up SuperSpeed devices no longer enumerate, and no SMMU fault is reported. Reverting only this commit on top of current master fixes it. The other commit seems fine. Adding the same property to the parent as well, like the NXP downstream tree does, also fixes it: &usbotg3 { iommus = <&smmu 0x4 0x7f80>; }; With that, SuperSpeed devices enumerate again. Could you please take care of a fix? Otherwise I think we should revert this patch. #regzbot introduced: 73c3b40e536d Thanks, Emanuele
