Error message when you try to uninstall or unload the driver for a multifunction USB device on a Windows XP-based computer: "STOP: 0x000000D1 DRIVER_IRQL_NOT_LESS_OR_EQUAL"

Support for Windows XP has ended

Microsoft ended support for Windows XP on April 8, 2014. This change has affected your software updates and security options. Learn what this means for you and how to stay protected.

Consider the following scenario:
  • You are running a Windows XP-based computer.
  • You have a multifunction USB device installed.
  • The driver for the device implements the USB selective suspend feature on one of the functions.
  • You try to uninstall or unload the driver for the USB device.
In this scenario, you may experience the following Stop error:
STOP: 0x000000D1 (parameter1, 0x00000002, 0x00000000, parameter4)
Note The value of the first parameter is the same as the value of the fourth parameter. However, this value may vary.
When the device driver is uninstalled or unloaded, the USB composite class driver (Usbccgp.sys) does not complete the pending USB Idle-Notification I/O request packets (IOCTL_INTERNAL_USB_SUBMIT_IDLE_NOTIFICATION) that were previously submitted by child device drivers. When these pending I/O request packets (IRPs) are canceled later, the child device drivers may have already been unloaded. Therefore, the computer may crash.
