ActivateDeviceEx() does not call ActivateDeivce(). In fact it works the
other way around ActivateDevice calls ActivateDeviceEx()!

You get ActivateDeviceEx to load the driver by doing the following:
1) put the following values into the registry under HKEY_LOCAL_MACHINE -
where doesn't really matter but it's usually under HKLM\Drivers
    "Dll"
    "Order"
    "Prefix"
How you create the reg key isn't relevant. (put it in a REG file and build
it into the image or add it from code with the Registry APIs, add it using
remote registry editor, etc...)

2) Call ActivateDevice or ActivateDeviceEx with the registry key created in
1. ActivateDeviceEx will create the devices Active key and add some of it's
own values, including the "Key" value which contains the drivers key passed
to ActivateDeviceEx. ActivateDeviceEx then adds the values you specify in
the REGINI structure.
