Here is what I remember.

DirectInput is used for the nonXBox joysticks. If the joysticks are of different types, I believe that will be the primary distinction. For identical types, the USB port number will be used.

For XBox controllers that are plugged in when the DS boots, they are port based. But if the DS is running and the joysticks are plugged in, the enumeration is based on insertion order. This makes things very confusing at times.
