Usb 2.0

I currently have USB 1.1 -What do I need to do to upgrade to USB 2.0?
Is is a simple PCI card? iIs it dependant on my Mobo? (please see my PC specs in my signature).
I'm gonna double post this into the Hardware Forum -I know that it is a hardware issue but I was hoping that the problemn would be ubiquitous enough that it might bleed into the Software forum.
Thanks for your time and patience.
Yours,

USB is by default part of the motherbaord. So if you want to upgrade it you need a new motherboard and this usually means a new CPU as well. Which is basicly like just buying a new computer.

You can buy PCI cards as well. Of course they're slower then normal USB2.0 but still faster then using USB1.1. Just so you know the only diffrence from USB1.1 to USB2.0 is speed. Anything that works with USB2.0 will still work just fine on USB1.1

Next time please only post this sort of question in the HW forum. It's not a SW issue at all.
