i have the older 17 inch non unibody macbook pros i have been moving over the week and when i was setting up, i accidentally plugged the wrong ac adapter into my usb hub. the next thing i notice, the usb is no longer working. keyboard, mouse, etc, not working, the other ones are initially, the wifi card went out to with the other usbs. i did two reboots and the wifi and other usb ports came back. the one where i plugged in the usb from the hub is dead is there an easy fix for this? im pretty sure there isnt but i had to ask. how much will apple care charge to replace the usb?
