Ehm.. seems I was a bit premature. With subsequent tests (and probably more 
stable driver) I can't reproduce the above, i.e. if I tear down
the device, set a new format, and reregister it, it shows up and I can stream

So now, as it seems, all that is left to do is to have custom icon/name in the 
control panel for the device. Is the inability of the

Vista/Win7 bug ?
