M32N0 USB Mass Storage after Cold Boot


I have a problem with my M32N0 running CE7. I need them with USB Client Mode Mass Storage Platform, but when i do a cold but that settings resets..(i know, its normal but my customer want a save system)

Now im searching the registry key to restore that settings with StartupCtl!

Can anybody help me and can tell me the registry path?
