I am currently using WM_DEVICECHANGE to be notified when new USB drives are connected to the computer. This works great for devices like thumb-drives where as soon as the device arrives it is ready to have files read from it. For devices like SD card readers it does not because the message is sent out once when the device is connected but no message is sent when a user actually inserts a card into the device.

Is it possible to detect the insertion of new media into an existing USB device without having to use polling?
