Serial port problem in OpenRB-150

When I used openRB-150 with Arduino IDE to control motors, it works well.
However, when I simply connect Dynamixel wizard 2.0 to openRB-150, the wizard cannot detect any motor. I guess this is a serial port problem at openRB-150.
But then if it is serial port problem, how can I control motors using arduino IDE?
I tried to factory reset the openRB but even cannot scan successfully.
Any suggestion?

I am using XM430-W350-T motor.

In order to use the OpenRB-150 controller with DYNAMIXEL wizard, you will need to reinstall the USB to DYNAMIXEL example sketch provided through the OpenRB board manager.
