TM4C123 KEYBOARD 描述符問題

您好,

       由於專案所需,根據以下這篇文章,TM4C123已經成功改成Keyboard功能

        http://bbs.eeworld.com.cn/thread-307666-1-1.html

        後來需要模擬成接近更真實的Keyboard,參考描述符文章(www.usblyzer.com/.../usb-keyboard.html)需增加ReportDescriptor和 Interrupt IN endpoint descriptor,修改usblib庫中的usbdhidkeyb.c , usbdhid.c ,目前嘗試加入這兩種描述符後,usb無法辨識,看起來似乎不是把所有參數都設置一樣就可行了,是否可以提供個建議或者有參考資料? 感謝您
