--------------------------------------------------------------------------------

Actually for doing the media keys and system control keys etc. you need to define a second interface. These keys do not fit into the standard keyboard report protocol.

Define the second interface to be in the consumer page and a general consumer control device. Then you can start listing the usages you want to offer.

I saw a Dell keyboard having 4 interfaces.
1. keyboard
2. media keys (Consumer Controls)
3. Power key
4. a command interface

如有这方面经验的哥们请帮忙啊!
大大得给分
非常感激!

刚刚做了Consumer Controls的项目，可以控制系统音量。仔细阅读HID1_11,Hut1_11文档，usb.org上有下载。参考其中usb键盘格式，填写正确的HID描述就可以了。
