SYMPTOMS

When you perform a surprise removal of a universal serial bus (USB) device on a Windows XP Service Pack 2-based computer, you may receive an error message that resembles the following:
STOP 0x000000CE (parameter1, parameter2, parameter3, parameter4)
DRIVER_UNLOADED_WITHOUT_CANCELLING_PENDING_OPERATIONS
Notes
  • The values of the parameters may vary.
  • A surprise removal means that you remove the device without first notifying the operating system.

CAUSE

This issue occurs because of a race condition in which the USB device driver is unloaded before the unwinding process of the dispatch routine runs.

RESOLUTION

A hotfix is available to resolve this problem.
