If you installed service pack 1, it will support both USB 1.1 and USB 2.0. &nbsp;If you want to know if your machine supports USB 1.1 or USB 2.0, look in device manager under USB controllers and see if the word &quot;Enhanced&quot; or &quot;USB 2.0&quot; appears - if they do, you have a USB 2.0 controller.

If you put you USB 2.0 Flash disk or anything else into the computer, it will say &quot;HighSpeed Device on an slow port&quot;. If everything will work just fine, without XP saying this, you have USB 2.0. Dont worry about whether your USB device supports USB 2.0, as it is almost everything today.<br />

Hope this helps,<br />

I accepted cwkhang's answer as his link led me to a lot of information, including using SiSoftware to determine which USB drivers I had.<br />
<br />
I have SiSoftware Sandra Utilities and it indicated that the drivers for both of my USB controllers were 1.1.<br />

Thank you all for your quick responses.
