Hmmm... I've had the same thing happen to my mighty mouse on an iMac.
The mouse wouldn't come alive until I unplugged and then replugged
again. I know that Solaris not OS X, but I had to remove some cache
files to remedy the problem along with a reboot.
Don't know if that will lead you to a solution tho.
