Hello, I usually have my MacBook Pro connected to a usb hub which has two hard drives, a printer and an iPhone charging cable attached to it. This USB hub has the option to be externally powered, I usually just have it draw power from my MacBook but today I needed some more power to hook up a bus powered external hard drive. Immediatly after hooking the power up to the usb hub my MacBook turned off and rebooted, shortly after that I noticed a burn smell coming from the usb hub. I quickly disconnected the USB cable from my MacBook but the damage had already been done, my MacBook Pro no longer recognizes any USB devices I connect. I have tried resetting PRAM and SNC and even reinstalled Mountain Lion, nothing has worked. It seems like the USB ports have been fried. I'm almost certain the logic board needs to be replaced, and since my warranty expired 3-4 weeks ago that would cost me at least 500-600 plus losing my computer for a week or so. But since this machine cost 1170 a year ago I'm leaning towards taking my losses and just buying a new computer and selling my MacBook Pro as a machine without working USB ports hoping I can get a couple hundred for it. Now before I make a rash decision I just wanted to ask if there was any advice from the Apple community. Thanks in advance.
