Did this issue return? Is it still happening sporadically? I have exactly the same issue (I'm even getting the same usb bus/device numbers). Sometimes it works fine first time. sometimes it fails until I power cycles a few times until it eventually detects the hardware. Unfortunately today I've restarted about a dozen times and it doesn't work so I'm using an external keyboard/mouse (which uses a different internal hub presumably). Unfortunately this doesn't appear to be a kernel/ubuntu bug but a hardware issue on the Macbook. What's really annoying is that the keyboard works in GRUB but fails to get initialized by the kernel.
