[ros-diffs] [mjmartin] 46867: [usb/usbehci] - Remove WorkItem code yet again as its not needed. - Set Ports PortChange to STATUS_CONNECTED when detecting insertion of new usb device. - Change UrbWorkerThread to use timer and wait so we dont waste cpu cycles. - Implement IOCTL_INTERNAL_USB_SUBMIT_IDLE_NOTIFICATION. - Upon receiving the IRP_MN_QUERY_DEVICE_RELATIONS with type BusRelation, stop processing the root hub IRPs, as at this point the hub driver has been informed of everything it needs to know about
