I'm confused, is my Macbook usb 2.0?
This is what I get when I look at "about this mac:" (attached image)
I'm confused. My ibook has only two USB ports, yet this image shows three USB busses.
Two of them (the first two in the picture) are at 12 Mb/ps, which would mean firewire 1.1.
But the last one, the "High speed USB bus" shows 480 Mb/ps, which is 2.0.
So what does this mean? does this mean one of my ports is 1.1 and the other is 2.0? How do I know where to plug in then? — And why then are there three busses and only two ports to plug in a USB devide through?
