Jan,
Thanks for the reply, but I'm afraid I may not have been clear on what I want to do.
The way I believe Generic HID works is:
1. Search for any HID device to see if at least one HID is connected.
2. If at least one HID is connected, search all connected HID devices and compare them to the VID/PID entered into the text boxes.
3. If my HID device is found (matches VID/PID), register it for notifications so that you can detect removal or re-attachment.
However, I would like to have some way to detect the attachment of my HID device without searching for it, and then registering it for notifications. Unless I am misunderstanding something, Generic HID requires the user to first manually search, then register a device, before any notifications are generated. Is this correct?
