connected device. For now this feature is only used by the 'disk' device to specify an alternative redolog filename of some image modes. - added new methods set_option() and timer() to the base class usb_device_c. The timer() method is periodicly called from the HC's frame timer code. - moved runtime device change stuff from the parameter handler to the end of timer() methods of all hubs. This makes sure that all parameters for the device have been set at connect time. TODO: this technique could also be used for the floppy and cdrom media change.
