If it's a Windows Script error, my inclinition would be that the VBS file is being executed and failing. Moreso, kbdhid.sys isn't a file which is unique to Logitech. It's a driver file that comes with Windows. To further make the point, I have an MS Natural Keyboard Pro and I have that file in my drivers directory. Therefore, that line is likely to execute on all systems, not just ones with Logitech keyboards, meaning the VBS file is being called on all systems as well.
