   It's been a while since I've installed Retaliation on a Mac. The error suggests that python's USB support. Libusb is a requirement but you'll also need USB support in Python.

   I found this post on Stack Overflow. It may help:

   Let me know if any of the suggestions work.

   I had the same problem as you @rabbadab. All I had to do was to install python using homebrew and then in a new shell:

   $ which python
   /usr/local/bin/python
   
   $ pip install pyusb
   Collecting pyusb
     Downloading pyusb-1.0.0b2.tar.gz (57kB)

     Running setup.py install for pyusb
   Successfully installed pyusb-1.0.0b2

   Thanks @jtheoof So you've had to install pyusb with pip? Do you think a change to the README would help? e.g.

   On a mac system, run the following commands:

   brew install libusb
   pip install pyusb

   Yes this is definitely the right steps. However I was not able to pass the kernel extension issues with Yosemite. See #20.

   To more correct @codedance, the install process on os x would be:

   brew install python # also installs pip
   brew install libusb 
   pip install pyusb
