Why is it that you believe that the DAT registry does not support plug and play? The interface was most specifically designed to allow that.
When a device is plugged in, the driver is loaded by existing OS mechanisms. It can then load the provider code (if needed). Whenever the provider module is loaded it registers itself with the registry, and it unregisters itself before it is unloaded. Keep in mind that loading/unloading DAT Provider is *not* synonymous with loading/unloading drivers. In fact I believe the intent is to have a single provider that supports multiple devices. Such a provider would simply register itself when it was loaded. I could see adding new interfaces to track which devices are loaded/unloaded for use *by* the DAT provider, but I do not see how that changes the function of the DAT registry, which is to support multiple DAT Providers.
