The normal way to get a mixture of USB 1 and 2 is to buy a PC with USB 1.0 installed as standard and then buy a new PCI card with USB 2.0 ports. I have such a PC myself.
By definition that means the PC is probably at least 2 years old as all new PCs come with USB 2.0 as standard and you can't buy USB 1.0 as an add-on any more.
You cannot see ANY physical difference between USB 1 and 2 ports.

Do you know that we're all in line for succession to the throne? Really?
Well, if forty-eight million, two hundred thousand, seven hundred and one people died I'd be Queen.
