how to do it with local/domain policy ?
As far as I know, there is no group policy to configure this. You could try to create a script to change this setting in registry.
You could find the device via GUID in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\ then find the Dword value PnPCapabilities (if it’s exist, create it). Then set the value to 38
Hope that helps

how about WIN8, I have followed all your suggestion, But still can't disable "Allow the computer to turn off this device to save power" for USB Power Management?
