USM is short for UltraSonic Motor. What this means is that your lens will
autofocus faster than standard models.
there are two different types of USM lenses. A Ring ultrasonic, is the one
you want to purchase. Then there are Micromotor ultrasonic drives that Canon
places into their cheaper lenses. Unfortunately, they also letter these
cheaper versions with USM as well. While these cheaper versions are quieter,
they don't however focus as quickly as a true ring ultrasonic lens.
Therefore, you need to check the lens specifications before purchasing to
ensure it is a ring ultrasonic lens, and not a cheaper version created for
what is rumoured to be marketing reasons.

It might be the correction everybody was expecting, I actually would rather
see it than worry about it all the time.
