No, I am sorry, it cannot. You'd know the interface is bound, but not necessarily to your driver or even the same "incarnation" of your driver. The fundamental problem is that we have no data structure describing the binding between a device and a driver so we cannot refcount that. As a consequence all refcounting just ensures that the device and interface data structures stay in memory, but we can make only very limited (read-only) use of them after a disconnection.
