How do I know if my computer has USB 2.0 or USB 1.1 support?

Most computers ship with built-in USB 1.1 ports that support USB 1.1 device speeds only. USB 2.0 support is usually added to a computer via a USB 2.0 add-in card, though some newer computers may have USB 2.0 ports built-in.

Please use the following steps to determine if your computer has USB 1.1 or USB 2.0 ports.

Note: Apple does not provide native support for USB 2.0; therefore, USB 2.0 speeds are not supported when using USB 2.0 devices on Macintosh operating systems at this time. Windows 98/Me
