I don't know it. But I think Rene told me that they don't like the specific 
inquiry command. Maybe with something else it may work.

The 2.11 version has some support for multidevice setup, but the concept and 
the implementation is flawed. That's why it doesn't work correct and the 
concept was changed for the 2.5 version.

The iPCR[1] is always (2.11 and 2.5) the sync stream plug. :)

The 2.11 version has uses two sync plugs but the 2.5 version has always exact 
one input and one output sync plug.

The quatafire uses a very old version of BeBoB. I don't think it will ever 
work in multidevice setup. Sorry about that. 

I'm using a reference design for developing. The things here work very good so 
far. The only problem I see is that the 'set' operation seems not correct 
yet. But the discovering works good.

cheers,
