usb 键盘，鼠标与游戏手柄枚举时候的区别

zzy3517

  这有一个例程。能枚举键盘。。。。我想改成枚举游戏手柄，，  有大神知道怎么改吗，  求帮助。。。。。。。。。。。。。。。。。

正点原子

貌似是有个ID可以区分类别的。具体要仔细看USB hid协议了

正点原子

看以上代码。HID_BOOT_CODE，HID_KEYBRD_BOOT_CODE，HID_MOUSE_BOOT_CODE
这几个，用来区分的类型。
 bInterfaceSubClass，为0表示自定义HID

额。。。   原子哥还没睡啊，，我去看看~~~~

读了。。原子哥~~   你的综合例程里哪个文件是usb枚举的啊。。。 表示没找到      T_T

修改HID报告描述符，有一个HID报告描述符生成工具

原子哥~~ 这是枚举后的吧，我现在还不能枚举呢。。。。。。~~~~(>_<)~~~~

楼主解决了没？    我是新手  也遇到了这个问题
