I am running 10.4.11. Firewire 400 will not power up or allow computer to recognize my I sight camera or power up firewire external hard drive. the 800 firewire port will not power up the external hard drive nor will the USB 2.0.... Iomega Ego 320gb. Usb 2.0 will power up smaller 80Gb drive I have but its not firewire drive.
I have reset psu with battery removal and presing start button while out and off. Have done archive and install of 10.4.11...have repaired permissions and verified disc.
