AFAIK, there is no such thing as a "USB 2.0 connector" either. I believe So-called "USB 2.0" cables merely meet the specification; well-made existing cables may also work just fine.
You have to wonder if USB 2.0 really does have a future. How many peripherals can we point to even now that take full advantage of the higher speed?
In contrast, there seems to be a growing number of 1394 devices kicking around.
