How to disable “allow the computer to turn off this device to save power” using C++?

Question

I my C++ application, I need to disable this option for the hubs that I can find in "Device Manager/Universal Serial Bus controllers".

I have iterated in these hubs using SetupDiEnumDeviceInfo and SetupDiGetDeviceInstanceId, but after that I don't now what to do, maybe it's not the best way, I don't know.

I am using Visual Studio 2010 with Windows 10.
