J0hn Demented, what are your Vendor & Device ID ? some people (including me) got working the card reader with only change this value in two places into kext; first the under Content Info.plist and other Info.plist under Content/Resources folder. I not sure if edit the Content/Resources/Info.plist is necessary but i changed the ID also when i installed this kext.
Regards.
