I installed 10.6.8 via software update on my MBP 17 2.6Ghz (2008? The model before unibody) and now I get kernel panic any time I plug in a mouse (wired or wireless) in the usb port. It appears to only be a problem with mice as I can plugin and use an external usb hard drive for time machine. Ideas anyone? I am at a loss and cannot do my work without a mouse. P.S I do remember messing with the iousbfamily.kext some time ago to fix dfu mode for iphone. Could this have anything to do with it?
