      Hi

       

      SCH FYI

       

      The 3rd DD port connect usb audio IC (ALC4021 Realtek)

       

      When I connect my borad to PC,  all devices can be recognize , including ALC4021

       

      when I download fireware to ALC4021,fireware can be download to flash. when the fireware download finish,the ALC4021 will reset to new code,

       

      but,PC can't recognize ALC4021,and PC pop the window

       

      I reconnect my borad to PC,all devices can be recognize , including ALC4021

       

      As a comparison

       

      last board version , I ues USB5744(Microchip) as HUB IC, the other SCH is the same with this version

       

      the last board have no this question.
