for both Hc2 and Hc protocol.
Arguments:
UsbBusDev - A pointer to bus controller of the device.
DeviceAddress - Represents the address of the target device on the USB,
which is assigned during USB enumeration.
EndPointAddress - End point address
DeviceSpeed - Indicates device speed.
MaximumPacketLength - Indicates the maximum packet size that the
default control transfer endpoint is capable of
sending or receiving.
DataBuffersNumber - Number of data buffers prepared for the transfer.
Data - Array of pointers to the buffers of data that will be
transmitted to USB device or received from USB device.
DataLength - Indicates the size, in bytes, of the data buffer
specified by Data.
Translator - A pointr to the transaction translator data.
TransferResult - A pointer to the detailed result information generated
by this control transfer.
Returns:
EFI_UNSUPPORTED
