设置配置和获取配置

仓库地址

仓库地址

USB 鼠标阅读顺序

• 枚举过程
• USB鼠标实现——设备描述符（一）
• USB鼠标实现——设置地址（二）
• USB鼠标实现——配置描述符集合（三）
• USB鼠标实现——字符串描述符（四）
• USB鼠标实现——设备限定描述符（五）
• USB鼠标实现——设置配置和获取配置（六）
• USB鼠标实现——报告描述符（七）
• USB鼠标实现——HID 报告的返回（八）

set configuration 和 get configuration

主机在获取完 device qualifier 后，又单独获取了几次设备描述符和配置描述符等，描述符的返回这里不再赘述。

标准设备请求中有 set configuration 和 get configuration。

只有在收到非 0 的配置值之后才可以使能非 0 端点，否则要禁用非 0 端点

设置配置

bRequest 域为 0x09

USB 控制端点收到的数据

0x0 0x9 0x1 0x0 0x0 0x0 0x0 0x0

• bmRequestType：0x00
  • 数据传输方向为 0，host-to-device
  • 标准请求
  • 请求的接收者为设备
• bRequest：0x09
  • SET_CONFIGURATION 设置配置请求。
• wValue：0x0001（LSB）
  • 低位：0x01 配置值低位为 0x01。
  • 高位：0x00 配置值高位为 0x00。
• wIndex：0x0000（LSB）
  • 低位：0x00
  • 高位：0x00
• wLength：0x00
  • 低位：0x00
  • 高位：0x00

无数据阶段

获取配置

bRequest 域为 0x08

USB 控制端点收到的数据

0x0 0x8 0x0 0x0 0x0 0x0 0x1 0x0

• bmRequestType：0x00
  • 数据传输方向为 0，host-to-device
  • 标准请求
  • 请求的接收者为设备
• bRequest：0x08
  • GET_CONFIGURATION 获取配置请求。
• wValue：0x0000（LSB）
  • 低位：0x00
  • 高位：0x00
• wIndex：0x0000（LSB）
  • 低位：0x00
  • 高位：0x00
• wLength：0x01
  • 低位：0x01 数据长度为 1 个字节
  • 高位：0x00

在数据阶段返回 1 字节的 set configuration 设置的值即可

注意事项

• 虽然枚举阶段可能没有用到 get configuration，但是在过 USB 认证的时候 CV test 会调用 set/get configuration 。所以最好还是实现这一对请求，不然后续会返回来查找 bug 。
• 只有在收到非 0 的配置值之后才可以使能非 0 端点，否则要禁用非 0 端点。
