This is hard to notice if you just drop in the code, as it only triggers on device enumeration and that likely only happens on startup or when a device change notification is received. I only noticed it because I temporarily modified my device enumeration code to run in a loop to see how fast (or slow) the WMI-based check would be. 386@http://virtualdub.org/blog/ MSDN has code to detect whether a controller device enumerated by the DirectInput API is also an XInput device, so that programs can avoid reporting the same controller twice when both APIs are supported:
