我有一個HID Report Descriptor(如附件1),在F/W已經build in在C8051F347中...
若main函式(附件4)裡將for loop拿掉且把Device(C8051F347)插入Host就會出現"無法辨識裝置"
反之,若沒有把for loop拿掉,把Device(C8051F347)插入Host就會出現"找到新的硬體可以使用"等訊息..
如果於Host再打開AP它會自動進行In & Out 動作...
因此,我想請問的是
1.沒有Report ID的HID Report Descriptor,該如何做IN/OUT控制呢??
2.為何在main中少了for loop就出現"無法辨識裝置"??
3.我並沒有在IN_PACKET或OUT_PACKET進行任何更新動作,那為何AP打開時Host與Device間會自動進行In & Out 動作??
我是使用Mouse Example進行修改
