用CH374操作遇到的問(wèn)題是什么呢？枚舉失敗、讀取不到鍵值、還是其他問(wèn)題呢？

可以控制LED燈亮，但讀不到鍵值

（1）讀不到鍵值與鍵值是什么內(nèi)容沒(méi)什么關(guān)系 （2）讀不到鍵值，CH374的返回狀態(tài)是什么？現(xiàn)在這個(gè)鍵盤(pán)的中斷上傳端點(diǎn)分析是否正確？

CH374的返回狀態(tài)是32（20H）

鍵盤(pán)的中斷上傳端點(diǎn)分析是否正確------這個(gè)不清楚在哪里能看得到

你可以通過(guò)BUSHOUND抓取該鍵盤(pán)的描述符,然后在程序中監(jiān)視下,看你獲取的數(shù)據(jù)是否和抓取的數(shù)據(jù)一致即可.還有你索取數(shù)據(jù)的端點(diǎn)是不是該鍵盤(pán)的中斷上傳端點(diǎn).
