I still do not know if I am going in the right direction. There is very little mention of the actual interface with the hardware. I recently found some references to "I/O commands" like "READ_PORT_XXX" and "WRITE_PORT_XXX" where XXX can be UCHAR, ULONG, USHORT, ULONG64. However, most references indicate these are to be used in Windows CE

Do I need something to tell WDF that the interface is an ISA bus and the interface is through I/O addresses?

Does WDF initiate a callback to the "EvtDeviceAdd" immediately after the WdfDriverCreate? van Dooren stated, "The EvtDeviceAdd function will be called each time the system determines that a new device has been connected". If not, how do I "tell" the system that our passive board is present
