Thanks! I've seen that "fix" but somehow forgot to try it out. It turns out, that it does work now and I'm even able to play an mp3 on 5 sound cards connected to the hub. Other workaround I found is to connect no more than 2 cards to one hub but in the same time, you can connect a second hub to the first one and put additional 2 cards there. I've successfully run 5 cards with the use of 3 hubs connected serially. -- Piotr Domagalski Mobile Systems Research Labs, Poznan University of Technology ------------------------------------------------------------------------------ Write once.
