 State transition interrupt detection
(*g_usb_PcdDriver.statediagram)(USB_NO_ARG, USB_STS_DEFAULT);
(*g_usb_PcdDriver.statediagram)(USB_NO_ARG, USB_STS_ADDRESS);
(*g_usb_PcdDriver.statediagram)(g_usb_PcdConfigNum, USB_STS_CONFIGURED);
(*g_usb_PcdDriver.statediagram)(USB_NO_ARG, USB_STS_SUSPEND);
 Detach detection
(*g_usb_PcdDriver.statediagram)(USB_NO_ARG, USB_STS_DETACH);
 Attach detection

Notes
1. Communication speed of a device is not notified when a reset is detected.
2. PCD does not issue this callback when the Set_Configuration request is received and the structure number isnot
changed
3. The ADDRESS state is notified when the Set_Configuration request is received and the structure number is 0.
