CANbus Termination Resistor
CANbus bus protocol there must be only two 120 ohm resistors on a bus.
No matter how many USB devices you connect, as long as it is on the same bus only two 120-ohm resistors are to be configured. These resistors should be at either ends of the bus.
After connecting CAN H and CAN L signal lines, use a multimeter to measure between CAN H and CAN L. The resistance between the two should be 60 ohms.
