我設計一塊板子,跟原始線路不同在更動了USB_H1_PWR_EN,但是使用原始code卻看不到有偵測到滑鼠插入,而進入android系統後,不更是不能驅動滑鼠,故不明為何?
我該如何讓板子看到輸入裝置滑鼠呢?
訊息如下:
紅字部份中是demo board沒有出現的訊息,故我認為是比較有可能有問題的描述,再麻煩大家幫忙了,感謝。

How the OTG_ID pin you connected?
hi,jimmychan:
感謝您的回答,經過測試後目前的確是 ID pin出問題,因為一開始我們用到mini-to-usb轉接器他沒控制ID,所以導致偵測不到滑鼠,現在ID pin拉low後,已經解決此問題,所以非常謝謝您指出此問題,感謝您。
