  • Question

  • When I pluged  in/off the USB device ,windows throw a message "WM_DEVICECHANGE" and called function of "WindowProc".  How do I receive the message "WM_DEVICECHANGE" in DDK driver Sample to set device online/offline on HVCC ??   I find two functions "OnDeviceArrival()" and "OnDeviceRemoveComplete()" in "DeviceBase.h", but they have never been used in DDK driver sample. When should I use they to set device online/offline on HVCC ? Thanks a lot.
