STATUS

Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article. This problem was first corrected in Windows XP Service Pack 1.

MORE INFORMATION

When you stop the 32-bit Cardbus device by using the Safely Remove Hardware tool in Windows XP, the power (VCC) for that device is not turned off. This behavior is by design on Windows XP, and is a limitation in the existing design of Windows. Because of the integration of the PCI driver and the PCMCIA driver, power cannot be turned off, otherwise the PCI configuration on the bus is lost.
