With the latest code I seem to run into a bit of a race with the hotplugging of USB cards. When I plug in a USB card I get the following problem.

So I guess hal is aware of the device before it "exists" or whatever. I appreciate this is likely not a pulse audio bug, but do you have any ideas about how/where to track down what is happening. Is it perhaps the fact that the loading of the usb-audio drivers them selves needs to happen before pulse can load the device but hal reports it immediately? Is hal reporting the device as being available too early or should pulse actually give udev or whatever time to load the modules? Thoughts appreciated.
