I need to create a WDM driver that emulates a device that is not present. The driver needs to be loaded when the O/S boots, opened and closed via SetupDiXXX
and CreateFile
, needs to respond to DeviceIoControl
, etc.
I have the driver coded, but XP refuses to load it. The system event viewer says:
The MyDevice service failed to start due to the following error: The service cannot be started, either because it is disabled or because it has no enabled devices associated with it.
Given that, I think the problem is in the INF file (reference below). Is it? How should I go about fixing it?
