USB 2.0 Benefits Data-Intensive Devices

Some USB devices, such as keyboards and mice, will show absolutely no improvement when released in USB 2.0 versions. However, you should see faster performance in other USB 2.0 devices, such as printers and scanners, where the data transfer rate makes a difference.
If performance is important to you, and you're planning to buy a USB printer, scanner, or other data-intensive device, consider waiting for USB 2.0. You'll need both a USB 2.0 version device and a USB 2.0 port on your PC to get the new device to work
