When you try to start your Microsoft Windows XP Service Pack 1 (SP1)-based computer, it may stop responding or "hang".


This problem may occur if you have both USB 2.0 devices and USB 1.1 FDD devices connected to a Windows XP SP1-based computer. Because Windows XP SP1 does not support the USB 2.0 Legacy BIOS, the USB 1.1 device driver does not work correctly.


To work around this problem, turn off USB 2.0 Legacy BIOS support in the computer's BIOS Setup utility. For information about using the computer Setup utility to modify the BIOS settings, contact the manufacturer of your computer.

Caution Incorrect settings in the computer BIOS may make the computer inoperable.


Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
