You can plug a USB 2.0 device into a USB 1.1 port, but you will only get 12 Mbps transfer speed. Similarly, you can plug a USB 1.1 device into a USB 2.0 port, but you will only get 12 Mbps transfer speed.

If your computer was built in 1997 or later, you probably have USB 1.1 support. The USB Implementers Forum provides a free utility download that examines your hardware to determine its USB capability. You can download it from: http://www.usb.org/data/usbready.exe If you have a computer with USB 1.1 support, you can use an expansion card that provides USB 2.0.

Manufacturers of USB 2.0 devices provide drivers that work with Windows 98 or higher. First you insert a CD that comes with product to install driver. Then, when you plug in USB cable, port will automatically configure for device.

The USB standard requires cables to operate at a length of up to five meters, but many hardware manufacturers guarantee their products to work only with much shorter cable that they provide. ----------------------------------------------------------- Resource Box: Copyright(C)2002 Bucaro TecHelp.
