Salaam Dear Tsuneo
In page 11 and 12 Firmware Programming Guide of D12:

when right side of Control Out Handler happens?
I wrote a test code but never this part happened!

In right side of Control In Handler when remaining bytes isn't zero Flowchart says that write control in buffer with data size of EP0Packet Size while you said me before write control in buffer With data size of remaining bytes in message '#108113 - VALIDATE_BUFFER'

You have mentioned protocol of sending Get_Descriptor by using Flags,Can you say please the protocol of sending Set_Descriptor/Set_address by using Flags?


Thanks and Regards
