When you upgrade a computer that has a Xircom Rex 6000 installed that uses the universal serial bus (USB) cradle, you may receive the following error message when the computer starts in Windows XP for the first time:
This error may also occur if you connect the USB cradle for the Xircom Rex 6000 to a computer that is running Windows XP, and then you begin the installation process during the hardware identification phase.
A Fatal System Error has occurred: 0x000000be (0x80129768,0x00129121,0xF96A4754,0x0000000B)
To resolve this behavior, contact the manufacturer of the Xircom Rex 6000 for an update that is compatible with Windows XP.
To work around this behavior, attach the device to the PC Card instead of the USB port by means of the cradle. This type of error is generated only when you use the USB port.
