Assume that you connect a USB composite device to a computer that is running Windows 7 or Windows Server 2008 R2. However, you may receive a Stop error message that resembles the following if the USB selective suspend feature is enabled:
This issue occurs because of an error in the Microsoft USB composite device driver (Usbccgp.sys). This issue occurs when the callback function of a client driver submits a D3 power request. However, Windows expects a D2 power request. Therefore, the idle IRP is completed and freed when the completion routine is run. In this case, Usbccgp.sys accesses the freed idle IRP after the callback function returns. This behavior causes an access violation, and the computer crashes.
