Hi,
I'm trying to use OSC to transfer data between a beaglebone black and a music software, pure data, running on my laptop. Everything works fine when I use my built in sound card, but with my FirefaceUC pure data freezes, the graphic interface no longer works and osc data is delayed. I'm positive it has something to do with de Fireface... Any ideas?

i use osx 10.7.5, firmware v115 driver v 2.21

Thanks
