Unfortunately, some devices (such as mice) have the cable built-in and thus could not possibly remain compatible.
How do you figure? The USB 3.0 standard was designed so that when you plug an older USB cable into it, it works as USB 2.0. That's what "compatible" means.
Obviously, the older devices won't be able to take advantage of new USB 3.0 features, but that doesn't somehow make them "incompatible".
