As we can see from recent bug reports, a lot of USB mass-storage devices cannot handle READ CAPACITY(16) commands properly. They send back garbage and are unusable as a result. Should we go ahead and set a flag on all these devices, telling the sd driver to try READ CAPACITY(10) first? That's a lot easier than adding more and more entries to unusual_devs.h.
