I have a MBP 2010. one of the USB ports is acting kind of funny. It will work some of my devices, like my iPad, external hard drive and some USB sticks. when I put my 8gig memory stick, it won't read or even detect it. When I plug my data cable for my phone, it won't even detect it. I don't know what's going on. I tested it out in bootcamp as well. It will detect it, but I won't be able to look at the contents within it.
