I have a Early 2008 24" iMac. On my USB ports, I have my wired keyboard, my external Seagate HD (for Time Machine), and I have a joystick. For quite some time, it seems like all of my USB devices keep disconnecting, and then reconnecting. This is particularly bad when it comes to my backups.
What can I do to stop this behavior from happening, and what more do I need to provide to help with this very annoying.
