Got a little more information from watching slow video:

pcib1: <ACPI Host-PCI bridge> on apci0
pcib1: _OSC returned error 0x10

I think that may be AE_LIMIT, but I can't be sure.

Do you know if ACPI could be the root cause, I do see the ehci device
created later on, so it does 'see' the USB bus, but maybe that above error
prevents it from finding the hub?  I don't know I'm wildly speculating here.

Maybe I should address the above first, then circle around to this.
