Well, we don't know if Kakashi can't, we just haven't seen him. Considering Tobi controlled Kurama when he attacked the leaf, Kakashi might be able to.
OT: Itachi probably could. Sasuke was shown to be able to suppress it while it was still in Naruto with 3-tomoe sharingan. I believe that any powerful Uchiha would be able to use it, if it was not contained in a jinchuuriki. (Of course, if they have MS, though the fact that Sasuke could suppress it with 3T sharingan it could just be skill-based, just my opinion.)
