Have you tested it > thoroughly? [sorry have to use another mail account, so far your mail didn't show up at my caviumnetworks account] I've tested it only on an EdgeRouterPro (Octeon II system, which I have on-site). octeon_ehci_device_init and octeon_ohci_device_init run way before ehci-platform and ohci-platform probe for devices. So everything should be initialized orderly. With current mainline (w/o these patches) USB doesn't work on my EdgeRouterPro due to an (inappropriate) OCTEON_IS_MODEL check. I'd say having the patches in linux-next for awhile wouldn't hurt.
