It wouldn't surprise me if by default qemu uses a paravirtualized USB port which expects a paravirt driver on the host, which of course OS X will not have. So I think you need to remove the USB device in the qemu guest and see if that works. If it does, then you can see about added the non-paravirtualized USB port to the guest, which ought to work.
