請教各位大佬，上面代碼中HIDRepDesc是官網(wǎng)默認(rèn)帶的，可以發(fā)送數(shù)據(jù)，并通過HidRawDataWatcher看到發(fā)送了什么數(shù)據(jù)；

改為HIDRepDesc2，這個我自定義的gamepad后，Enp2BlukIn發(fā)送的數(shù)據(jù)HidRawDataWatcher就看不到了。

好像只要指定了report id就無法發(fā)送數(shù)據(jù)了，我在main中已經(jīng)指定了UserEp2Buf的第一個字節(jié)是1了。

您好，

先大致看上去，配置描述符下的HID描述符中，wDescriptorLength段用于描述HID報告長度，這兩個字節(jié)沒有修改成修改后的描述符長度。

改HID報告，應(yīng)當(dāng)修改上述位置的報告長度，還應(yīng)該修改中斷服務(wù)函數(shù)處理中獲取報告描述符請求的返回數(shù)組，有時還要注意端點包長是否也要對應(yīng)修改，端點包長還可能和緩沖區(qū)定義有關(guān)。

與其相關(guān)的幾個點都可以全局搜索下看看。

@TECH29

多謝回復(fù)。描述符長度已經(jīng)修改了，我貼的代碼沒改。

經(jīng)過調(diào)查發(fā)現(xiàn)是HIDRepDesc中的所有的report的數(shù)據(jù)大小未和端點buffer的尺寸一致所致。
