我需要获取有关从不同鼠标单击和释放的 Wheell 的信息。我在嵌入式设备上工作，可以访问原始形式的所有数据 - 字节流。

AFAIK 所有传输的字节都在 HID 报告描述符鼠标中进行了描述。我有 HID 报告描述符和来自 2 个不同鼠标的传输帧，但我不确定如何理解它们：

HID 罗技：

Logitech 帧 4 字节，首先用于按钮：

00 00 00 00 : Button OFF (on release), X=0, Y=0, Whell=0
01 00 00 00 : Button 1 ON, X=0, Y=0, Whell=0
02 00 00 00 : Button 2 ON, X=0, Y=0, Whell=0

报告描述符格式在 HID 的设备类定义中进行了说明。鼠标也包含在 HID 使用表文档中。所有这些都可以在 usb.org 的 HID 页面上找到 -> http://www.usb.org/developers/docs/hidpage/

我在这里写了关于嵌入式 HID 的博客，包括报告描述符 -> http://www.circuitsathome.com/category/mcu/arduino/usb-shield/hid

此外，如果您只需要鼠标的某些功能，例如 X、Y、滚轮和 3 个按钮，您可以将其初始化为启动设备。然后，任何鼠标都将具有相同的报告结构（请参阅启动鼠标），您可以将其硬编码到您的应用程序中。
