外部固件模式:程序是例子程序USBDISK.C.那些描述符也都是USBDISK.H中的.這是什么原因

計算機在要配置描述符時好象你傳輸?shù)牟粚?09 04 00. 04不是配置描述符標志.00長度為0怎麼處理.

計算機要要兩次配置符嗎?在收到 80 06 00 02 00 00 09 00 返回了9字節(jié)的配置描述符,然后又收到

80 06 00 02 00 00 ff 00 反回9字節(jié)的接口描述符

這樣不對嗎?

請問這個時序?qū)?為什么沒人解答呀?

這樣給你說,你的描述符上傳有問題,計算機給要什麼數(shù)據(jù)你只要正確上傳就行了,不要管計算機為什麼這樣給你要數(shù)據(jù).

引用回復:這樣給你說,你的描述符上傳有問題,計算機給要什麼數(shù)據(jù)你只要正確上傳就行了,不要管計算機為什麼這樣給你要數(shù)據(jù).

我知道計算機要什么給什么,我問的就是我給的對不對?

都是要配置描述符,你卻返回不一樣,而且第二個為什麼返回端點描述符. 09 04 00 00 02 08 04 50 00 根本不是設(shè)備描述符

80 06 00 02 00 00 09 00 是要設(shè)備描述符還是要配置描述符?協(xié)議上說這是要配置描述符.可我返回配置描述符后也不對呀

謝謝,我找到原因了,驅(qū)動程序安裝有問題.成功了.
