The assertion is here:

   1233 		 * busdev now points to the direct descendent of the
   1234 		 * controller ("atabus" or "scsibus").  Get the
   1235 		 * controller's devhandle.  Hoist it up one more so
   1236 		 * that busdev points at the controller.

   1238 		busdev = device_parent(busdev);
   1239 		devhandle = device_handle(busdev);

   1241 		ofnode = devhandle_to_of(devhandle);

Since pluggable USB devices almost certainly have no associated OF
nodes, this is probably a matter of:
