From the FAQ:

Does the Superbook require MHL? Nope. The Superbook doesn’t use MHL technology--instead, it uses Displaylink technology

Check out http://displaylink.com/downloads/android for more info!

I haven't personally tried a Displaylink device yet but It looks like it works well with USB 2.0.

Ok, thanks, that makes sense. It's actually just a connection for the display and the keyboard, after all.
