Hi, what’s the difference between your design and devkit? As below said in Design Guide:
The USB SS hub design uses a Realtek RTS5411-GRT device. The hub device has been customized using internal fuses with the Realtek tool. A design intending to duplicate the developer kit hub implementation should customize the hub as follows:
Power enables (DPS1/2/3/4_PWR) set to be active high
Charging feature disabled

Please find attached schematic of USB hub and jetson nano.
Hi, please check and compare your design to reference based on Design Guide and ref schematic, we don’t provide such review support, and also the fuses settings as mentioned.
