\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.

//urb_list For use by current owner of the URB.
//anchor_list membership in the list of an anchor
//anchor to anchor URBs to a common mooring
//dev Identifies the USB device to perform the request.
//ep Points to the endpoint's data structure. Will
// eventually replace pipe.
//pipe Holds endpoint number, direction, type, and more.
// Create these values with the eight macros available; u
// sb_{snd,rcv}TYPEpipe(dev,endpoint), where the TYPE is
// "ctrl", "bulk", "int" or "iso". For example
// usb_sndbulkpipe or usb_rcvintpipe. Endpoint numbers
// range from zero to fifteen. Note that "in" endpoint two
// is a different endpoint (and pipe) from "out" endpoint
// two. The current configuration controls the existence,
// type, and maximum packet size of any given endpoint.
//status This is read in non-iso completion functions to get
// the status of the particular request. ISO requests
// only use it to tell whether the URB was unlinked;
// detailed status for each frame is in the fields of
// the iso_frame-desc.
//transfer_flags A variety of flags may be used to affect how URB
// submission, unlinking, or operation are handled.
// Different kinds of URB can use different flags.
// URB_SHORT_NOT_OK
// URB_ISO_ASAP
// URB_NO_TRANSFER_DMA_MAP
// URB_NO_SETUP_DMA_MAP
// URB_NO_FSBR
// URB_ZERO_PACKET
// URB_NO_INTERRUPT
//transfer_buffer This identifies the buffer to (or from) which the I/O
// request will be performed (unless URB_NO_TRANSFER_DMA_MAP
// is set). This buffer must be suitable for DMA; allocate it
// with kmalloc or equivalent. For transfers to "in"
// endpoints, contents of this buffer will be modified. This
// buffer is used for the data stage of control transfers.
//transfer_dma When transfer_flags includes URB_NO_TRANSFER_DMA_MAP, the
// device driver is saying that it provided this DMA address,
// which the host controller driver should use in preference
// to the transfer_buffer.
//transfer_buffer_length How big is transfer_buffer. The transfer may be broken
// up into chunks according to the current maximum packet size
// for the endpoint, which is a function of the configuration
// and is encoded in the pipe. When the length is zero, neither
// transfer_buffer nor transfer_dma is used.
//actual_length This is read in non-iso completion functions, and it tells
// how many bytes (out of transfer_buffer_length) were transferred.
// It will normally be the same as requested, unless either an error
// was reported or a short read was performed. The URB_SHORT_NOT_OK
// transfer flag may be used to make such short reads be reported
// as errors.
//setup_packet Only used for control transfers, this points to eight bytes of
// setup data. Control transfers always start by sending this data
// to the device. Then transfer_buffer is read or written, if needed.
//setup_dma For control transfers with URB_NO_SETUP_DMA_MAP set, the device
// driver has provided this DMA address for the setup packet. The
// host controller driver should use this in preference to setup_packet.
//start_frame Returns the initial frame for isochronous transfers.
//number_of_packets Lists the number of ISO transfer buffers.
//interval Specifies the polling interval for interrupt or isochronous transfers.
// The units are frames (milliseconds) for for full and low speed devices,
// and microframes (1/8 millisecond) for highspeed ones.
//error_count Returns the number of ISO transfers that reported errors.
//context For use in completion functions. This normally points to request-specific
// driver context.
//complete Completion handler. This URB is passed as the parameter to the completion
// function. The completion function may then do what it likes with the URB,
// including resubmitting or freeing it.
//iso_frame_desc[0] Used to provide arrays of ISO transfer buffers and to collect the transfer

\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
to reflect the final xfer_len value.
