How to detect a new device was installed ? (What message/event?) Basicly I've got an app that uses webcam(s). When they unplug, I get a nice event that the device is unplugged. But how can I detect that a (usb) device is being connected ? I assume there's a windows-message indicating a new device connection, but I don't have a clue where to find documentation about this. (MSDN isn't always as clear as you'd like it to be :)) Ciao, Led

Thanks, exactly what I was looking for. After 35 minutes I couldn't find anything, and while you posted I found it myself. Stupid me....
