Most computers ship with built-in USB 1.1 ports that support USB 1.1 device speeds only. USB 2.0 support can be added to a computer via a USB 2.0 add-in card, though most newer computers 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.
