+/****************************************************************************
+ * Name: usbhost_complete
+ *
+ * Description:
+ *   This function implements will the complete() method of struct
+ *   usbhost_class_s.  In the interface with the USB host drivers, the class
+ *   will queue USB IN/OUT transactions.  The enqueuing function will return
+ *   and the transactions will be performed asynchrounously.  When the
+ *   transaction completes, the USB host driver will call this function in
+ *   order to inform the class that the transaction has completed and to
+ *   provide any response data.
+ *
+ * Input Parameters:
+ *   class - The USB host class entry previously obtained from a call to
+ *     create().
+ *   response - Response data buffer
+ *   resplen - Number of bytes of data in the response data buffer.
+ *
+ * Returned Values:
+ *   On success, zero (OK) is returned. On a failure, a negated errno value is
+ *   returned indicating the nature of the failure
+ *
+ * Assumptions:
+ *   This function may be called from an interrupt handler.
+ *
