MX-64 problem when running DynamixelSDK read write example

Hi everyone,
I was trying to run the protocol 2.0 read_write example from DynamixlSDK with the MX-64 servo using u2d2. After making and running read_write, there seems to be a problem called “[TxRxResult] There is no status packet!”.

Have any of you encountered or resolved this problem? Thank you in advance!

Either the baud rates used in the program and out on the OS or on the servo do not match. Or if you are using Linux you may not have set up the proper permission on the COM port yet.
