  *   - argument #2 is target endpoint

  *   error occurs)
- * - if the call is answered with EOK, first argument of the answer is buffer
- *   hash that could be used to retrieve the actual data
  *
  * Some special methods (NO-DATA transactions) do not send any data. These
  * might behave as both OUT or IN transactions because communication parts
  * where actual buffers are exchanged are omitted.

- * The mentioned data retrieval can be done any time after receiving EOK
- * answer to IN method.
- * This retrieval is done using the IPC_M_USBHC_GET_BUFFER where
- * the first argument is buffer hash from call answer.
- * This call must be immediately followed by data read-in and after the
- * data are transferred, the initial call (IPC_M_USBHC_GET_BUFFER)

  * For all these methods, wrap functions exists. Important rule: functions
  * for IN transactions have (as parameters) buffers where retrieved data
