As per Jonas' reply, its not clear libusb has been installed. zadig works for me and makes the install process much easier (if you want super easy, go with Linux)
I did have some notes on this but they were in Bitbucket and didn't survive their mercurial purge and I've not found hosting so here is a copy/paste: ## USB Driver installation ## Windows usb drivers can be downloaded from http://zadig.akeo.ie/ (older versions at http://sourceforge.net/projects/libwdi/files/zadig/). 1. Download zadig_2.1.1.exe 1. Run it 1. Plugin in LCD into USB port, zadig will detect it (16C0 - 05DC) 1. Select "libusb-win32 (v1.2.6.0)" (do not use "WinUSB (v6.1.7600.16385)" - see screenshot 1. Click Install Known to work with Windows 8.1 (64-bit) with Python 2.7 32-bit. If you are finding the docs are lacking be great to get a PR open with a fix. It's faster for me to copy/paste the above than to check the current status
