    I am thinking about a Canon 300D and I am able to buy
    a 300D/Rebel with normal 18-55 EF-S lens, and the
    Japanese version with a 18-55 USM lens.
    (Yes, I can buy all three versions here).

    As far as I know, those two lenses are optically
    the same, but the USM has a faster (?) or
    better (?) mechanism for focussing.

    Can someone give more information about the difference
    between the two lenses?

    That is the difference. Optically it's the same, mounts the same, externally
    looks the same.

    Yes, but I hope someone can be more specific about
    how much faster the focussing will be.

    My 75-300 IS is USM but it's slow however, my "L" lenses are USM and they
    are FAST in other words, micro USM are slower than ring type USM.
