Ok, I think I've addressed all of Alan's issues. This version of the patchset: - Reorders the PCI IDs correctly. - Moves the port switchover from the EHCI PCI probe to the xHCI PCI quirks. - Makes both the xHCI and EHCI driver switch the ports over when the pci_resume functions are called. - Adds a new kernel parameter for which ports should be switched over. - Documents said kernel parameter in Documentation/kernel-parameters.txt I've verified that the PCI quirks code does correctly run before the EHCI probe completes: [ 5.525756] calling pci_apply_final_quirks+0x0/0x106 @ 1 [ 5.531196] pci 0000:00:14.0: USB 3.0 ports that are now enabled under xHCI: 0xf [ 5.538572] pci 0000:00:14.0: USB 2.0 ports that are now switched over to xHCI: 0xf [ 5.546240] pci 0000:00:1a.0: EHCI: BIOS handoff [ 5.570969] pci 0000:00:1d.0: EHCI: BIOS handoff ...
