MacBook Pro USB Ports Not working I have a MacBook Pro mid 2009 computer. Connecting my usb flash stick doesn't do anything, I tried both ports but not working. I tried connecting an iPad, the iPad charges but it doesn't open show in iTunes for syncing.

One thing to note is that Windows on VMWare recognized the devices when it is active, but not MacOSX. That means the problem is not hardware related.
