- added external USB hub
* ported generic hub code from Qemu * devices can be connected at runtime only with textconfig * FIXME: wx ParamDialog doesn't like removing runtime parameters on disconnect * TODO #1: dynanamic runtime dialog for USB on Windows * TODO #2: code cleanup: USB code should have one static function only for most of the init_device() code
