How do I restore my keyboard and mouse?
I deleted my caches from my library folder and have lost my keyboard and mouse. If I reboot with both unpluged from USB I have them for a short time before I loose them again. Using Snow Lepord. My goal was to speed up my Mac. But, it has caused huge problems. Any suggestions? Is there a SL "achieve & install" feature that will repair my keyboard and mouse without deleting my harddrive?
Mac Pro, Mac OS X (10.6.8)
