Pegasus on Linux: Proof of Concept with python

TL-DW;

$ # Plug pegasus, find bus/dev id and fix permissions
$ lsusb -d 1cda:03e8
Bus 008 Device 011: ID 1cda:03e8
$ sudo chown $(id -un).$(id -gn) /dev/bus/usb/008/011
$ # Setup virtual env
$ virtualenv -p python3 venv
$ . venv/bin/activate
$ pip install python-can-pegasus/
$ # Output is time stamp, flags, frame ID, payload.
$ # CTRL-C to stop
$ # 1 NSS evo3 and 1 NSX on CAN bus
