To help determine your system’s USB capabilities you can download a free USB evaluation utility from the following site: www.usb.org
This program will examine your system and inform you of your computer’s USB capabilities.
For a general rule, if your PC was manufactured before 1996, it probably does not include USB. If the machine was manufactured in 1997 or later, it may support USB 1.0 . Most computers manufactured after 1998 support USB 1.0. Systems available since 2001 probably support USB 2.0.
With some PCs, you may need to connect an adapter (PCI or CardBus) to connect USB peripherals. Read your system documentation if you’re not sure there is a USB port.
