    I am looking for a way to get Windows to notify my application when a new USB device is attached or detached from the system. The ideal solution would be a callback method of some kind, but a small low overhead polling loop could also work. Thank you.

      Windows sends a (rather, a few) WM_DEVICECHANGE message to all top level windows when *anything* in the device list changes. You can also register for notifications for a specific device class, usign RegisterDeviceNotification() Note: There's a bug in Win98 that makes UnregisterDeviceNotification crash.
