leadfingers Posted May 18, 2011 Share Posted May 18, 2011 I know this topic has been bashed to death but I thought I'd add the fix that worked for me. Once at my desktop I had use of USB keyboard & mouse but trying to connect any USB drive would crash my system. Step 1: Copying "IOUSBMassStorageClass.kext" Open Finder /System/Library/Extensions Copy "IOUSBMassStorageClass.kext" Locate "IOUSBFamily.kext" Right-click Select "Show Package Contents" Find & Open "Plugins" folder Paste "IOUSBMassStorageClass.kext" Step 2: Repairing Permissions Click "Spotlight" Type in "Disk Utility" Select the drive you're using Click "Repair Permissions" when completed reboot Step 3: Download & Install updated IOUSBFamily.kext Go to http://developer.apple.com/hardwaredrivers...d/usbdebug.html Download the latest IOUSBFamily.kext for the version of OSx you're using (sadly Apple requires free sign-up) For 10.5.6 I chose "IOUSBFamily.kext" v3.2.7 Once downloaded dluble-click to open .dmg double click on "IOUSBFamily-327.4.0.pkg and follow instructions Allow it to reboot when required Use "-f" switch when rebooting Your Mileage may vary but this worked for me on an nForce2 and nForce3 system.
