USB Host 配置

ArtInChip 提供了两路 USB Host 端口和一路 USB Device 端口，需要分别进行配置：

USB Host Contoller 配置
ArtInChip 在一个 USB Host 端口中提供了下列 Host Contoller，在软件上需要需要分开配置：
- 配置 EHCI 控制器
USB Interface 驱动配置

完成 USB Host Contoller 配置后，系统可以正确识别插入 USB 总线的 Device 设备。USB Device 有各种不同类型，例如 U 盘、键盘鼠标、无线网卡。在 USB Device 中以 Interface 为单位提供不同类型的功能。如需使用 USB Device 具体功能，需配置不同类型 USB Interface 的驱动。
不同类型 USB Interface 驱动的配置可查看：
- U 盘配置

配置 EHCI 控制器

针对 USB 2.0 (High Speed) 的 EHCI 控制器，配置流程如下：

在 menuconfig 中配置设备。
使能 USB 端口，并且配置当前 USB 端口为 Host 模式：
```
> Board options
   [*] Using Usb0
       Select Usb0 mode (Host)  --->
```

在 menuconfig 中配置 CherryUSB 驱动。

使能 CherryUSB 驱动，并且使能 Host 模式：

> Local packages options
   > Third-party packages options
       [*] CherryUSB: tiny and portable USB host/device stack for embedded system with USB IP  --->
           [*]   Enable usb host mode  --->

U 盘配置

在 menuconfig 中使能 CherryUSB 中 msc 类型的 Host Class 驱动，并且使能对应实例模板：

> Local packages options
   > Third-party packages options
       [*] CherryUSB: tiny and portable USB host/device stack for embedded system with USB IP  --->
           [*]   Enable usb host mode  --->
               [*]   Enable usb msc driver  --->
                   [*]   Use msc template

插入 U 盘，会自动挂载到 /disk 目录：

HID 设备配置

在 Menuconfig 中使能 CherryUSB 中 hid 类型的 Host Class 驱动，并且使能对应实例模板：

> Local packages options
   > Third-party packages options
       [*] CherryUSB: tiny and portable USB host/device stack for embedded system with USB IP  --->
           [*]   Enable usb host mode  --->
               [*]   Enable usb hid driver  --->
                   [*]   Use hid template

插入鼠标设备，自动创建线程监听鼠标数据：

aic /> [I/USB] Switch port 1 to OHCI

[I/usbh_hid] Register HID Class:/dev/input0

UVC 设备配置

在 Menuconfig 中使能 CherryUSB 中 uvc 类型的 Host Class 驱动，并且使能对应实例模板：

> Local packages options
   > Third-party packages options
       [*] CherryUSB: tiny and portable USB host/device stack for embedded system with USB IP  --->
           [*]   Enable usb host mode  --->
               [*]   Enable usb hid driver  --->
                   [*]   Use uvc template
               [*]   Enable third party  --->
                   [*]   using chry memory pool
                   [*]   using chry ring buffer

插入 USB 摄像头：
