Usage是HID Report Descriptor的一部分,可用来表明一个特殊的控制,或一组控制。每个Usage包含一个usage ID, usage name, 和一个详细的描述。Usage由16bit的Usage page和16bit的Usage ID组成: Usage page Usage ID Usage ID 0为保留。ID 1到0x1F为”top level” collection保留,这些ID虽然对于Application不是必须...
Usage Pages The types of behaviors that a HID device may support. Undefined Usage A constant that indicates a device's usage doesn't correspond to one of the defined behavior types. Interaction Types Generic Desktop Usages related to generic desktop devices, such as mice, joysticks, and keyboard...

The HID Power Devices specification indicates 0x84 and 0x85. There is at least one macro in /usr/include/dev/usb/usbhid.h which removes the high order bits. Perhaps we need to do that when using the values. Perhaps this macro: #define HID_USAGE2(p,u) (((p) << 16) | u) The ...
头文件在VC中有好多，不同的头文件功能不同，你也可以按自己的需要来写头文件。 不懂的头文件你可以把鼠标移到它前面按F1 跳到MSDN里面查看头文件的功能。 头文件的使用 ，在库里有的头文件你可以在你要写的C或C++文件开头加上#include<stdlib.h>语句就行 自己定义的头文件也差不多 ...
