How to list programmable wake devices with C++

Question

I'm trying to achieve the results of the following command that lists all programmable wake devices, or those that can be set/reset to wake the system:

powercfg -devicequery wake_programmable

I need to do the same from a C++ service. I'm using the code similar to this, but it gives me a smaller list. Here's how I call DevicePowerEnumDevices:

if(DevicePowerEnumDevices(index,
    DEVICEPOWER_FILTER_DEVICES_PRESENT,
    PDCAP_WAKE_FROM_D0_SUPPORTED |
    PDCAP_WAKE_FROM_D1_SUPPORTED |
    PDCAP_WAKE_FROM_D2_SUPPORTED |
    PDCAP_WAKE_FROM_D3_SUPPORTED |
    PDCAP_WAKE_FROM_S0_SUPPORTED |
    PDCAP_WAKE_FROM_S1_SUPPORTED | 
    PDCAP_WAKE_FROM_S2_SUPPORTED |
    PDCAP_WAKE_FROM_S3_SUPPORTED,
    buff, &dwBuffSize))
{
    //Got it
}

What flags am I missing for wake_programmable?
