Listing serial ports in Mac OS X and Python 3

Question

I'm having trouble listing available serial ports and I really need help debugging this. In Python 2.7.5 the COM-ports are listed correctly while PySerial returns an empty list in Python 3.3.5.

I found one other lonely soul with the same problems on the internet (no answers), but the problem doesn't seem to be popular at all - maybe it's my system?

I'm using Mac OS X 10.9.2 and installed python and python3 via homebrew. I updated everything just now. PySerial is at version 2.7 in both pip and pip3.

The output:

Python 2.7.5 (default, Nov  4 2013, 18:04:45) 
[GCC 4.2.1 Compatible Apple LLVM 5.0 (clang-500.2.79)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> from serial.tools import list_ports
>>> list_ports.comports()
[['/dev/cu.Bluetooth-Incoming-Port', 'n/a', 'n/a'], ['/dev/cu.Bluetooth-Modem', 'n/a', 'n/a']]

Python 3.3.5 (default, Mar 10 2014, 13:25:50) 
[GCC 4.2.1 Compatible Apple LLVM 5.0 (clang-500.2.79)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> from serial.tools import list_ports
>>> list_ports.comports()
[]

Answer 1

For the moment I'm resorting to the following method. The PySerial tools are broken.

>>> import glob
>>> glob.glob('/dev/tty.*')
['/dev/tty.Bluetooth-Incoming-Port', '/dev/tty.Bluetooth-Modem']
