Enumeration Issue in the Custom HID operating at High Speed mode (using ULPI USB3300)

[Srg_Prakash]

Hello,

        I am working in the Project to Communicating Custom hid in the High speed mode. I'm using the   ''openH7XXI-C" board with ULPI USB3300 module for the high speed communication.

       Device manager shows "Device Descriptor Failed". But  I am actually configure it correctly. I am also cross check the,  1) CLOCK- that is 60MHz

                  2)HS Global Interrupt 

                  3)Pin Configuration 

                  4)Various Descriptor in the custom HID(device descriptor, configuration descriptor, endpoint descriptor,    interface descriptor and report descriptor)

                  5) HS & FS bit interval -1ms

                  6) output buffer size - 64bytes

       can anyone have idea about this problem?...

Hello,

       I found that issue. This problem arise from Connectivity of the ULPI USB3300 with STM32H743IIT6 board.

 I just plug in and plug out the ULPI USB3300 and STM32H743IIT6 board and reset the Controller then I connect the USB cable to the HUB (CPU) , then HOST (PC) recognize the device. So now I can transmit up to 1024Bytes through the Custom HID.
