access with Python Thanks to Aaron Blondeau for this As he says: "I am working on controlling a Blink1 from an Android. In order to understand how the set feature calls work without wearing out the usb port on my Android I have created a python script that uses the pyusb library. The code is as follows if you wish to share and save some time for other folks."
