@roverh ,
Sorry for the delay! Just checking up on you to see if you are still experiencing the same problem. Did you install the driver? Sometimes with Mac OS you need to install it twice. If you switched the USB cable with a different one it may also not work. Let me know if you continue to experience issues.
