The kernel failed to get the USB descriptor. I'm not sure now whether it's a bug in IOMMU or rather in USB controller. Judging from the dmseg output, it's handled by ohci-pci. Adding both USB and IOMMU guys to Cc for better clues. -- You are receiving this mail because: You are the assignee for the bug.
