socket format?

you've got A, B, C, Micro, and Mini connectors all that conform to 3.0 and 3.1 spec...

Alas the standard needs standardised....

And A is always the same socket regardless of version while B is not. It's a mess.

> And A is always the same socket regardless of version

Even this is technically incorrect: USB-3 A-type sockets, though backwards compatible for f/m and m/f connecting with USB-2, have 5 more contacts compared to USB-2 type A sockets.

Returning to this topic, maybe...

USB-C-3 for the new connector format.

USB-C-2 for some (many) cellphones.

USB-Micro-2 (for many phones).

USB-Mini-2 (older phones)

- Edit -

I changed my mind, the connector is more important than the wire version.
