List Members, 2400c/6 gig/80 RAM system 9.1 I have tried installing Apple's USB card support 1.4.1 via extracting the files with Tome Viewer and when I boot I get the folowing msg. " The USB support extension is curently disabled. Please refer to the USB DDK documentation to enable this extension." The extensions was enabled as viewed in Extenison Manager. I have seen mention in the archives of a MCE USB Extension, not sure what this is really or when it is needed. Any help apprecitiated. FYI, I did the cardbus enabling via cutting the two yellow wires near the ram. All else works fine. My Airport and Ethernet card works fine. Thanks!!!
