    Exactly as the title says, on my MacBook (Late 2007 2.2ghz, 4gb RAM, 500 GB HDD) all the USB ports are unresponsive, but only within OS X. I can do the various boot up commands, and the keyboard and mouse work their, but within OS X, they do not. I have a bootable backup, in which the USB ports do work though, so this is a software issue rather than a hardware issue. I want to try and avoid reinstalling OS X, but I am afraid it may come to that.

    Have you reset your PRAM or SMC?

    Otherwise, backup then archive and install.

    Ok, I archived and installed and everything is back to normal.
