- 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 the device. The next SCE request will remain pending until another devices is connected. - Implement ExecuteControlRequest for all control related communications to/from usb devices. - Remove GetDeviceDescriptor and GetDeviceStringDescriptor as no longer needed. - Fix implementation of Direct Call function CreateUsbDevice. - Implement Direct Call functions InitializeUsbDevice and GetUsbDescriptors. - Misc rearranging and clean up. svn path=/trunk/; revision=46867
