You need to add the trigger during kernel compilation. Do you have the tools for compiling a new kernel for your plug? They are usually included in your Development Kit disc.  Smiley

If you have purchased a plug, then more or less your plug provider has also given out a development disc which contains relevant documentation to help you out. Otherwise, there are also instructions from PlugWiki on how to perform kernel compilation:
