WakeFromD0, WakeFromD1, WakeFromD2, and WakeFromD3
Each of these DEVICE_CAPABILITIES structure members indicates whether the device can awaken in response to an external signal that arrives when the device is in the specified state.
For a device that supports all four device power states (D0, D1, D2, D3) but can awaken only from states D0 and D1, the WakeFromD0 and WakeFromD1 bits are set, and the WakeFromD2 and WakeFromD3 bits are clear.
