Question, it's a simple one, I think...

USB2 ---- it's it downward compatible?

For example, can you use USB2 with the regular old USB? I understand A & B... But I don't understand the whole thing.

I never thought that hard about it, and my dear S.O. isn't around to answer my question, which is actually on behalf of an off-board friend that I can't visually see what he's talking about...
