USB core error import on mac about retaliation

[codedance]

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

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
