- Save PortNumber in child device extensions as its needed when PNP request device capabilities. - Handle IOCTL_INTERNAL_USB_SUBMIT_URB request by creating a new Irp and passing the Urb down to the miniport. - Now working with our ehci driver, we at least see a usb driver and can browse directory in Windows, though doing so results in assert as ehci doesnt support transfers over 5 Pages yet. Fix coming soon. svn path=/branches/usb-bringup/; revision=51672
