Don't use Auto Sharpen it's not good. Use the USM feature and prescan at up to 3 times the magnification if you need to see very fine detail. Also note that you don't want to be sharpening the image to the extent that it looks as if it has been over sharpened. Remember this is the beginning of the process NOT the end. You're trying to reduce NOT eliminate the softening effects that occur when scanning.

You can also use the USM with Descreening to help reduce the grainy effect that occurs with some B&W negative films when scanned at high resolution
