I know 2.0 and 3.0 are chipsets that’s why I used the word “traditional”. I wasn’t sure if the current USB Apple uses is USB-A or what.
I want them to go to USB-C as well, but don’t really mind Lightning to USB-C for now as long as they include those cables and adapters with products going forward. I assume next year’s iPhones will utilize USB-C... Maybe?
USB-A and USB-C are physical connectors. What everyone describes as simply USB is USB-A. The big barn shaped connector that printers use/used is USB-B.
USB 1.0, 2.0, 3.0 etc. can all be transported over any of the above.
