I have designed a custom carrier board for jetson nano and I used the Jetson_Nano_Carrier_Board_OrCAD_Schematics which is the design guide. For the usb part I have not used the hub which is also an option in the design guid. But the usb does not work and does not detect the mouse or keyboard, although it does when it is connected to the original carrier board. I have read some threads in the forum and I have not found any clear answer. Is there any need for configuration in the software or any modification in the hardware?
