How to dynamically load and unload a PnP WDM Driver

Hello,

I know legacy style drivers can be loaded at any time with the Service
Control Manager APIs, but PnP style drivers can't.

My application uses a temporary driver that I want to load only when my
application is running, and unload it when my application finishes it's task.
How can I load a driver at runtime without actually installing it?

Thanks,

PnP driver? impossible.

The Toaster Bus sample can also show you how to mark the device as
non-present, assuming you own the bus that enumerated the devnode. The real
question is why? Why do you care if the driver is unloaded?

Worst case you can uninstall the devnode when you are done, but that's a
little heavy-handed.

If you need to load and unload a driver dynamically from an application,
then just write a non-PnP ("legacy") driver. They still have their place.

Some people have the impression that everything marked "legacy" is
automatically bad. It ain't so.

Unfortunately, keyboards can't be legacy this days... Or if they are, they
only initialize at boot.
