Get_inverter_temp(), ROS node, error

Hi,
I am using a ODrive 56v connected to two motors, i can get both motors to run via the odrivetool and arduino setup, but when i tried switching over to the ros node:

I have run into trouble using the usb connection to the board from my laptop.
I installed the node as per instruction, and im pretty confident it is installed correctly, but i keep getting this error when i try to run “rosrun odrive_ros odrive_node”

I can’t seem to figure out how to get the leftwheel temperature it’s talking about.
