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.
- create config parameters for USB depending of the defined number of ports
- removed obsolete comment
- bx_param_num_c flag USE_SPIN_CONTROL now available for all config interfaces
* 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
