I had an issue with the USB port on my 2012 MBP after the Mavericks update and I was sure it was the update that was causing the error. I finally to it to Apple and come to find out I had a faulty logic board. They replaced it for free and I was only without my baby for 24hrs.
Hope you find a fix soon!!
