I am having a problem with my macbook pro 13'' bought in 2011. It had been working so far until these few days, when my USB port does not work. It tells me that the usb port hard ware was not working and was not installed properly. It had been working very well, and I could back up also. Can someone help? Resetting PRAM only worked once and then it did not help afterwards.

MacBook Pro, OS X Mountain Lion (10.8.3)
