Connecting native port to Mac through USB isolator


I am connecting the native port of a Due to OSX through a B&B Electronics UH401 USB isolator ( The port is recognized, but I cannot communicate with it. I already have an external power supply. Programming through the programming port works fine, and I can also communicate with the Due through that.

More info: - The port changes name from /dev/tty.usbmodem2621 to /dev/tty.usbmodem621 when I pass the usb through the isolator. - The programming port is always called /dev/tty.usbmodem621 - It seems to work fine on my friend's Linux pc.

Does anybody have any ideas for a solution?

Best regards

Have you ever identified a solution? I too have this same problem.
