自制USB HID笔设备仅适用于Windows 7/Linux
我用STM32F4微控制器制作了一个USB HID笔设备。我的设备在Windows7或Debian7（Linux）上运行得非常好 问题是=>它在Windows 8、8.1、10等上不起作用 我的设备被识别为“HID手写笔”，usb视图没有错误，管道是打开的，但我的光标不会移动。 更糟糕的是，我没有看到任何数据包与UsbLyzer一起进出 编辑：自制USB HID笔设备仅适用于Windows 7/Linux,windows,embedded,usb,hid,stm32,Windows,Embedded,Usb,Hid,Stm32,我用STM32F4微控制器制作了一个USB HID笔设备。我的设备在Windows7或Debian7（Linux）上运行得非常好 问题是=>它在Windows 8、8.1、10等上不起作用 我的设备被识别为“HID手写笔”，usb视图没有错误，管道是打开的，但我的光标不会移动。 更糟糕的是，我没有看到任何数据包与UsbLyzer一起进出 编辑： On windows 7 = PowerDevice = stay @ D0 On windows 8 = PowerDevice = D0 1s

我改变了很多事情：
- 改变我做填充物的方式
- 我不再发送扫描时间了
- 。。。。也许其他人有很多东西没什么变化
