The USB A connector stayed the same between USB 1, 2 and 3. Yet most manufacturers voluntary distinguished them by giving USB 1 and 1.1 a white insert in plug and port, USB 2 a black insert and USB 3 a blue one This was neither standarized nor enforced, yet it worked remarkably well in the real world Then we decided to just have no markings at all on USB C cables. On the ports at least we occasionally get little thunderbolt or power symbols | ||

The exterior of the USB A connector stayed the same. The number of pins increased when we went from USB 2 to 3. So, even in this case, it’s slightly more complicated. The colors helped because the capabilities were very different between the ports. But when the USB IF increased the number of options (and reduced the size of the connector), different colors became impossible to do. The problem is that there are too many uses for one connector. But this is wha we wanted - a reduced number of standardized connector/power options. | ||
