What is USB Controller

I have a desktop running Windows Me and want to add some USB 2 ports. On websites I can find 4 port USB 2 PCI cards for about £10, but some are called "USB 2 PCI cards" and some are called "USB 2 PCI Controller cards". What does the "controller" part mean?

I don't know what it means technically, but as far as I can tell, it is another way of expressing the same thing. Differing naming strategies for marketing reasons.

basically every usb port needs to be attached to a controller, due to your m/c probably having maximum amount of usb ports assigned to it's onboard controller a usb expansion cards come usefully with it's own controller, so yes it's the same thing as any usb expansion card has a contoller whether mentioned or not.
