The app will basically install the devcon utility (which is what is actually enabling and disabling the device) into the c:\temp folder. The app is a simple toggle, if the SDHost Device is enabled, it will disable it. If it is disabled, it will enable it.
(note: it usually takes longer to enable than to disable)
