I reported the orignal bug based on my experience with a USB-printer/scanner combo from Brother (DCP 165C), but although that printer still works, I have not managed to get the scanner driver working again since Maverick. My other scanner however, a USB Canon which is supported by the open-source sane drivers rather than Brother's broken proprietary stuff, shows the same behaviour though, now and then.
