c++ - how to determine keyboard disconnected in DirectInput

Question

I am monitoring HID connections using EnumDevices(..., DIEDFL_ATTACHEDONLY). When I disconnect a game controller it no longer shows up in the callback. However, when I disconnect the keyboard, it still shows up in EnumDevices.

I've looked through the API, but I don't see where else to query if a device is connected.
