When a computer that is running Windows XP is accessing USB 2.0 hard disks under heavy stress conditions, you may receive a bugcheck 0xFE message similar to the following:
In a USB Driver bugcheck, the first parameter is a USB bugcheck code that has the following arguments:
Argument 1: 00000002, BAD_URB. The USB client driver has submitted a USB Request Block (URB) that is still attached to another Input/Output (I/O) request packet (IRP) that is still pending in the USB driver.
Argument 2: 8162ea78, Address of the pending IRP.
Argument 3: 81707950, Address of the IRP that is passed in.
Argument 4: 8156db7c, Address of the URB that caused the error.
This behavior occurs because in the NT Kernel two threads try to start an I/O operation on the same packet.
