My mom has a new (to her) MacBook (7,1) and she THOUGHT that one of her USB ports was messed up. She has a phone that she plugs in and a hub. The hub worked but the phone tether didn't. Or vice versa. The phone worked or a mouse worked. Etc etc. At any rate, she couldn't get her phone to show up in one port but it worked in the other. I looked in the System Profiler and one is OHCI and the other is EHCI. Does that make a difference?
And to make it worse, when she got here, both ports seemed to work. So now she has no problems. But the problems she had before continued for more than a couple days so it was persistent.
