透過修改 vision_board_tinyusb project 來測試 USB Host 功能
程序源代碼在 
https://github.com/KunYi/sdk-bsp-ra8d1-vision-board/ 
branch usbh

整合DOOM with MIPI 2.0 的版本

整合 NES with MIPI 2.0 
https://github.com/KunYi/sdk-bsp-ra8d1-vision-board/tree/game/projects/nes/vision_board_mipi_2.0inch_nes

A 修改 SDK 內的 libraries/components/tinyusb/lib/rt-thread/tusb_config.h

```c
#if   BOARD_DEVICE_RHPORT_NUM == 0
--#define CFG_TUSB_RHPORT0_MODE     (OPT_MODE_DEVICE | BOARD_DEVICE_RHPORT_SPEED)
++#define CFG_TUSB_RHPORT0_MODE     (OPT_MODE_HOST | BOARD_DEVICE_RHPORT_SPEED)
#elif BOARD_DEVICE_RHPORT_NUM == 1
#define CFG_TUSB_RHPORT1_MODE     (OPT_MODE_DEVICE | BOARD_DEVICE_RHPORT_SPEED)

//--------------------------------------------------------------------
// DEVICE CONFIGURATION
//--------------------------------------------------------------------
--
++#define CFG_TUD_ENABLED               (0)
#ifndef CFG_TUD_ENDPOINT0_SIZE

++//--------------------------------------------------------------------
++// HOST CONFIGURATION
++//--------------------------------------------------------------------
++#define CFG_TUH_ENABLED             1
++#define BOARD_TUH_RHPORT            0 // FULL SPEED
++#define BOARD_TUH_MAX_SPEED         OPT_MODE_FULL_SPEED
++// Default is max speed that hardware controller could support with on-chip PHY
++#define CFG_TUH_MAX_SPEED     BOARD_TUH_MAX_SPEED
++
++//------------------------- Board Specific --------------------------
++
++// RHPort number used for host can be defined by board.mk, default to port 0
++#ifndef BOARD_TUH_RHPORT
++#define BOARD_TUH_RHPORT      0
++#endif
++
++// RHPort max operational speed can defined by board.mk
++#ifndef BOARD_TUH_MAX_SPEED
++#define BOARD_TUH_MAX_SPEED   OPT_MODE_DEFAULT_SPEED
++#endif
++
++// Size of buffer to hold descriptors and other data used for enumeration
++#define CFG_TUH_ENUMERATION_BUFSIZE 256
++
++#define CFG_TUH_HUB                 2 // number of supported hubs
++#define CFG_TUH_CDC                 0 // CDC ACM
++#define CFG_TUH_CDC_FTDI            0 // FTDI Serial.  FTDI is not part of CDC class, only to re-use CDC driver API
++#define CFG_TUH_CDC_CP210X          0 // CP210x Serial. CP210X is not part of CDC class, only to re-use CDC driver API
++#define CFG_TUH_CDC_CH34X           0 // CH340 or CH341 Serial. CH34X is not part of CDC class, only to re-use CDC driver API
++#define CFG_TUH_HID                 0 // typical keyboard + mouse device can have 3-4 HID interfaces
++#define CFG_TUH_MSC                 0
++#define CFG_TUH_VENDOR              3
++
++// max device support (excluding hub device): 1 hub typically has 4 ports
++#define CFG_TUH_DEVICE_MAX          (3*CFG_TUH_HUB + 1)
++
++//------------- HID -------------//
++#define CFG_TUH_HID_EPIN_BUFSIZE    64
#++define CFG_TUH_HID_EPOUT_BUFSIZE   64
++
++//------------- CDC -------------//
++
++// Set Line Control state on enumeration/mounted:
++// DTR ( bit 0), RTS (bit 1)
++#define CFG_TUH_CDC_LINE_CONTROL_ON_ENUM    0x03
++
++// Set Line Coding on enumeration/mounted, value for cdc_line_coding_t
++// bit rate = 115200, 1 stop bit, no parity, 8 bit data width
++#define CFG_TUH_CDC_LINE_CODING_ON_ENUM   { 115200, CDC_LINE_CODING_STOP_BITS_1, CDC_LINE_CODING_PARITY_NONE, 8 }
```

B 將 libraries/components/tinyusb/lib/rt-thread/tusb_rt_thread_port.c 
tinyusb task 內的 device task 改為host task

```c
    (void) parameter;
    while (1)
    {
--        tud_task();
++        tuh_task();
    }
```
C 然後透過修改 class vendor 驅動，去適配XBoxOne控制器
　 主要是參考 class HID 然後修改
D 這時 HOST 的驅動已經完成，然後透過引入 projects/usb/vision_board_tinyusb/board/tinyusb/xpad_joystick.c 讓程序可以接入按鍵信號處理

目前可以偵測 D-PAD 上下左右 與按鍵 A B X Y, Start, Select

使用XBoxOne 控制器，玩DOOM
