Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "C:\Python27\lib\site-packages\usb\core.py", line 819, in find
raise ValueError('No backend available')
ValueError: No backend available
You need to install libusb-1.0, libusb-0.1, or openusb as a backend to pyusb. Is this a Windows machine?
If so, you can download a simple installer here: http://www.craftedge.com/products/libusb.html
