Thanks to Pete Peterson (@ipetepete on Twitter) for these instructions for setting up K40 Whisperer on a Mac computer
- Python 2.7 (this works nicely if you use virtualenv)
- Inkscape (build from source using brew)
- Must be run as
root-see below for more info
This did not work using the Quartz binary for Inkscape. Only by building from source did it work correctly. Suggested approach is installing using Homebrew:
brew install caskformula/caskformula/inkscape
Suggested approach is to use Virtualenv and install Python 2.7 even if your system is currently running 2.7.
Install requirements:
pip install -r requirements.txt
Run K40Whisperer
sudo python k40_whisperer.py
Why does this need to be run as root?
In general all devices require elevated permissions. To allow PyUSB access to a certain device as non-root, some work needs to be done, namely; create a user-group, set perms to the device when connected as belonging to the group, add your user to the newly created user-group.

This can potentially be automated, but more work needs to be done.
