- \brief A URB Descriptor (URBD) holds the state of a bulk, control,
-  interrupt, or isochronous transfer. A single URBD is created for each URB
-  (of one of these types) submitted to the HCD. The transfer associated with
-  a URBD may require one or multiple transactions.
-
-  A URBD is linked to a EP Queue Head, which is entered in either the
-  isoc, intr or non-periodic schedule for execution. When a URBD is chosen for
-  execution, some or all of its transactions may be executed. After
-  execution, the state of the URBD is updated. The URBD may be retired if all
-  its transactions are complete or if an error occurred. Otherwise, it
-  remains in the schedule so more transactions can be executed later.

-   \brief This function does the setup for a data transfer for a host channel and
-  starts the transfer. May be called in either Slave mode or DMA mode. In
-  Slave mode, the caller must ensure that there is sufficient space in the
-  request queue and Tx Data FIFO.
-
-  For an OUT transfer in Slave mode, it loads a data packet into the
-  appropriate FIFO. If necessary, additional data packets will be loaded in
-  the Host ISR.
-
-  For an IN transfer in Slave mode, a data packet is requested. The data
-  packets are unloaded from the Rx FIFO in the Host ISR. If necessary,
-  additional data packets are requested in the Host ISR.
-
-  For a PING transfer in Slave mode, the Do Ping bit is set in the HCTSIZ
-  register along with a packet count of 1 and the channel is enabled. This
-  causes a single PING transaction to occur. Other fields in HCTSIZ are
-  simply set to 0 since no data transfer occurs in this case.
-
-  For a PING transfer in DMA mode, the HCTSIZ register is initialized with
-  all the information required to perform the subsequent data transfer. In
-  addition, the Do Ping bit is set in the HCTSIZ register. In this case, the
-  controller performs the entire PING protocol, then starts the data
-  transfer.
-
-  @param _ifxhc Information needed to initialize the host channel. The xfer_len
-  value may be reduced to accommodate the max widths of the XferSize and
-  PktCnt fields in the HCTSIZn register. The multi_count value may be changed
