Okay... so the OS boots and runs fine, gotcha.the OS still works. the cd drive & usb ports went out.
Did your USB hub's power plug come unplugged? Have you added some other device that gobbles juice? Your mouse and keyboard still work, so try swapping their connections with those of your CD or USB drive.cd drive and usb drive that dont work. dont know why, but they just stopped working.
What do you mean they don't work? Do you mean you cannot boot the Mac off of a USB connected device?I'm running moutain lion with a cd drive and usb drive that dont work. dont know why, but they just stopped working. i tried the Option + Power method but only get 1 option to show which is the hard drive. NEED HELP PLEASE!
