Hi I got a problem!!! My first usb port (the lead usb port) is stopped working. I acedentally put a usb hub with 12v power supply in it, into my MBP. It is a 15" MacBook Pro mid 2010 2,53ghz i5. (it's the one with a ssd slot) Any suggestion of what to do? ps. I have treid to run a hardware test on it but it didn't came with any result. Hope for some useful help.
