Execute USB mass storage command through the transport protocol.
| Context | The USB Transport Protocol. |
| Cmd | The command to transfer to device |
| CmdLen | The length of the command |
| DataDir | The direction of data transfer |
| Data | The buffer to hold the data |
| DataLen | The length of the buffer |

| typedef EFI_STATUS(* USB_MASS_GET_MAX_LUN) (IN VOID *Context, IN UINT8 *MaxLun) |
Get the max LUN (Logical Unit Number) of USB mass storage device.
| Context | The context of the transport protocol. |
| MaxLun | Return pointer to the max number of LUN. (e.g. MaxLun=1 means LUN0 and LUN1 in all.) |
| EFI_SUCCESS | Max LUN is got successfully. |
| Others | Fail to execute this request. |
| typedef EFI_STATUS(* USB_MASS_INIT_TRANSPORT) (IN EFI_USB_IO_PROTOCOL *Usb, OUT VOID **Context OPTIONAL) |
Initializes USB transport protocol.
This function initializes the USB mass storage class transport protocol. It will save its context in the Context if Context isn't NULL.
| UsbIo | The USB I/O Protocol instance |
| Context | The buffer to save the context to |
| EFI_SUCCESS | The device is successfully initialized. |
| EFI_UNSUPPORTED | The transport protocol doesn't support the device. |
| Other | The USB transport initialization fails. |
