Qjackctl doesn't know the firewire backend yet. For other issues with it 
you'll have to check with it's author.

Your device uses a mixer control API that is not supported yet. Since I 
don't have any Presonus devices to test with, it might take a while 
before that is implemented. Also note that the Firepod/FP10 doesn't have 
a built in mixer.
