Now 3, since I had missed all the libusb's -> libusbx's

I'm also thinking we may want to add something to mention that libusbx's 
1.0 API aims at being compatible with libusb's, as this is likely the 
first question developers will have, though I'm not exactly sure how we 
want to formulate that. We may want to mention that we only aim at being 
compatible with 1.0.8, as if we add a new API and libusb duplicates it 
under a different name, we're not going to change our initial API just 
for the sake of compatibility.
