// In addition you can call SetCompletionDetails if you need to wait for the end of

|
// the request or want to complete an irp. You call AddUSBRequest to add the request to the queue.
|
|
// Once the request is completed the CompletionCallback is invoked. The CompletionCallback
|
|
// will take care of any completion details which have been set. If the request is cancelled, the
|
|
// CancelCallback routine is invoked.
