+
+Yeah, it's a hack, but it is only temporary until Alan's patches
+reworking this area make it in.  We really should not care what devices
+below us are doing, especially when we do not really know what type of
+devices they are.  This patch relies on the fact that the endpoint
+devices do not have a driver assigned to us.
