USB Port not high speed?
I recently plugged my iPod into my 13" MBP, and got a warning that I was connecting to a slow USB connection, and I should plug it into a high speed port. Transfer speeds are extremely slow. I tried both USB ports with the same result. I have not had this issue in the past.
System profiler does not indicate the ports are high-speed:

I had no reason to look at profiler before, so I can't say if it described them as high-speed or not, but transfer speeds were good. Any ideas?
