FIX: Stop error 0x9F or 0xFE in Usbhub.sys occurs when asynchronous transfer is in progress with a USB device in Windows 7 Service Pack 1 or Windows Server 2008 R2 Service Pack 1


When asynchronous transfer is in progress with a USB device in Windows 7 Service Pack 1 or Windows Server 2008 R2 Service Pack 1, the USB Enhanced Host Controller may become unresponsive when any of the following events occur:
  • A USB device is removed unexpectedly (surprise removal).
  • A Plug and Play rebalance is triggered in the USB tree.
  • The system powers down.
  • A USB device is gracefully removed.
When any of these events occurs, you may receive Stop error 0x9F or Stop error 0xFE in Usbhub.sys.


This problem occurs because the USB Enhanced Host Controller is supposed to issue an interrupt to cancel the pending asynchronous transfer. However, the unresponsive controller never sends out the interrupt, and a Stop error occurs.
