Default Identifying USB 2

Hi

What is the easiest way to know if a PC has USB1.1 or USB2 (using software)?

I've looked around Windows XP on several PCs and I can't tell....

Default Identifying USB 2

Click Start | Run | Devmgmt.msc
In device manager it will state something like ??host controller (USB1.x) or
extended host controller (USB2.x)!

There are only 3 types of controller standards;
USB 1.x UHCI (Universal Host Controller Interface)
USB 1.x OHCI (Open Host Controller Interface)
USB 2.x EHCI (Enhanced Host Controller Interface)
