Jetson nano power connection

I am student for jetson nano.
I wonder for connection 2dynamixel motor with U2D2 to jetson nano.
is that okay for give 5V adapter to jetson nano and give 12V adapter to u2d2?
Because, when i only connect jetson nano and U2D2 via USB, only u2d2 get turn on, motors are not.
when i run motors by computer, i always give power to U2D2
But, jetson nano need their own 5V power so is it okay to give another power for U2D2?

Hope someone has such experience can be shared. We don’t have suggestion on this. You can refer to the Nano devkit carrier board spec and Jetson nano produce design guide for the interface info. Both docs are in DLC.
