SYMPTOMS
BPStress.exe is part of the Hardware Compatibility Test (HCT) Fault Tolerant test kit. When you run BPStress.exe, the computer may stop responding and you may receive a &quot;bugcheck&quot; error message on the UsbhFdoCleanup process.



CAUSE
This behavior may occur when BPStress.exe causes a failure on a node during the stress test, and then moves to a backup node. During this failover mode, the USB host controllers and root hubs are removed, and this causes the error.

No USB devices must be attached to the computer for this error to occur.
