Hello, I own a Macbook Pro. Everything worked fine until the other day when my external HD USB started going too slow, as if it suddenly were USB 1.0. I tried it in another computer and it works fine. Also I connected to my computer another USB 2.0 device (a flash drive) and same problem, therefore its clear that the problem is the macbook and not the device. No other devices connected at the same time. No HUBs. Is it possible that both USB 2.0 ports could be ruined at the same time and stop working as fast as they should? Is this something I can fix with, lets say a firmware update or something like that? Of course I could stop using the USB ports and connect all my external drives to the firewire ports, but that is not the point, especially when they've been working just fine until now. Thanks!
