SYMPTOMS
When you are running Windows Millennium Edition (Me) on a computer that supports the Advanced Configuration and Power Interface (ACPI) specification and you insert a CardBus card, the following symptoms may occur:
 * The mouse pointer may alternate rapidly and continuously between a &quot;regular&quot; pointer and a &quot;busy&quot; (hourglass) pointer.
 * The computer may perform very sluggishly.
 * The CardBus card never finishes being initialized.



CAUSE
On an ACPI-enabled computer that uses certain Texas Instruments CardBus controllers, inserting a CardBus card that does not support power management can result in a continuously asserted Power Management Event (PME) signal by the controller. This causes the card to be continuously re-enumerated.
