No USB port on OS X

My WiPy is in the extension board which is connected via USB to my MacBook running OS X 10.9.5. I put
Code: Select all
from machine import UART
import os
uart = UART(0, baudrate=115200)
os.dupterm(uart)
into boot.py, triggered a reset i.e. reboot but there's no /dev/tty.usbmodem* device. I haven't found any other mention of this issue in this forum so I'm suspecting I'm doing something wrong even though it's straight out of the docs?

There should be a usbmodem device regardless of the settings in boot.py. This is because the USB serial is always on and running, even with no wipy in the dock. So there must be some hardware or driver problem.

Assuming it's an FTDI chip on the Wipy, try the driver from this page

I've had this problem too since day one - no /dev/tty.usbmodem* device on OSX. Tried installing the driver linked to above without success. I've also tried dropping the specified baud rate in boot.py. LoPy then fails to boot and needs safe resetting. Help!
