USB 通信协议（键鼠方案）

1 设备描述

多模键鼠方案自定义了一个 USB 通信协议，当使用此功能时，设备被初始化为多接口设备。

1.1 USB描述符

device_des

  • interface0作为标准键盘通信接口，ep1 in作为标准键盘上报通道

  • interface1作为复合通信接口，通过report ID区分，ep2 in作为通信上报通道，ep2 out作为通信输出通道

    • ep2最大支持64B, 键盘鼠标vendor对应不同的report ID，vendor消息通信格式如下

      ana_inout

设备描述符

uint8_t DeviceDscDat[] = {
	0x12,           /*  bLength; */
	0x01,           /*  bDescriptorType; */
	0x00, 0x02,     /*  bcdUSB; */
	0x00,           /*  bDeviceClass; */
	0x00,           /*  bDeviceSubClass; */
	0x00,           /*  bDeviceProtocol; */
	0x40,           /*  bMaxPacketSize0; */
	0x6d, 0x04,     /*  idVendor; */
	0x77, 0xc0,     /*  idProduct; */
	0x00, 0x01,     /*  bcdDevice; */

	0x03,           /*  iSerialNumber; */
	0x01            /*  bNumConfigurations; */
};

控制描述符

控制描述符只有一个，内容包含了双接口描述符，每个接口描述符子集具有hid描述符，每个hid描述符指定了端点，通过不同的hid report描述符进行对应描述
