If you're really trying to innovate on confusing people, I would suggest some things to deliberately make it harder for people. To take just a first pass over your suggestions - creative use of case, and letters/numbers that could easily be confused. USB 4.01 (USB 1.0 speeds) USB 4.0L (USB 1.0 speeds again) USB 4.0i (40 Gbps) USB 4.0l (80 Gbps) USB 4.0f (charging only) Store pages become useless. Search doesn't help. Can you imagine asking the Office manager to buy some USB 4.0l cables for your high-speed 80Gbit devices -- but what turns up is a USB 1.0 cable.
