Not knowing what to do can end up in blue screening the system, and if your driver is loaded on boot and executes that code, you now have a problem. If you process a request in a different thread which is running in another process context, you would not be able to read user mode memory across process boundaries. For example: Block I/O (open, strategy, close) Character I/O (open, write, close) Autoconfiguration requests, such as probe and attach, do not result directly from a user program, but result from At these times, those “drivers” who work with memory can only access memory that cannot be paged out. https://msdn.microsoft.com/en-us/windows/hardware/drivers/gettingstarted/

This works just like “printf” and it prints messages out to the debugger or debug output window.

The root bus driver object is responsible for keeping track of the devices connected on any bus in your entire computer, and ensuring that the data gets to where it is But I got a question: it is easy to understand that Example_Create/Example_WriteNeither/Example_Close should be triggered when I run the user mode application , But Example_UnSupportedFunction is also triggered, and this is The autoconfiguration software (specifically, the bus's confl1 interface) calls the driver's probe, attach, and slave interfaces.
