locating multiple av/c devices w/ the same GUID
by Tommy Schell

Hi,

I'm having trouble placing 2 of the same av/c devices  (class  
"IOFirewireAVCUnit") on the Firewire bus, and having them be  
identified by
my program.
If I have just 1 or the other device on the bus, they are found using  
my program or by running the IOFirewireLibBasics sample.
If I put both devices on the bus, the IOFirewireLibBasics sample  
can't find either of them.  Then I have to restart my Mac in order
to be able to find 1 device again.

The devices, right now, have the exact same GUID.
Could this be the cause of the problem, and is there any  
workaround?  Such as, is there a way to have the devices identified
by node id?

Thanks, Tommy Schell
