This project aims to be a simple USB/HID user application space (hence no system drivers needed) 100% python package (without C extensions). Initially targeting simple HID devices management.
The vision for this project is to be something similar to PySerial or PyParallel but for USB/HID hardware enthusiasts.
AdvantagesCurrent limitations
All python code, using ctypes
Top level handling of HID events (usage events calling hook function handlers)
Depending on your application you might find these limitations
Installation Instructions Windows
Windows only (so far…)
Maybe speed. I’ve had feedback by some users that speed is not a problem for high data throughput, but I think you might hit some Python limits if you are require any real time processing.
The most convenient way of installing is using easy_install or pip, I recommend to do this once you are familiar with the library as you might loose track of the example source files, but you can take a look to the example or the source browsing the github repository.
If using a source package (.zip) from PyPi un-zip your file, or get the source from the main repository and run the familiar setup.py install command line is sufficient, setuptools or distribute (for python 3) are required.
OtherSo far only Windows OS it’s supported.
Using pywinusb.hidView the ./examples directory for some (ok, few right now) scripts. These show, for instance, how to use pywinusb.hid to handle events from HID class devices usages events.
Latest code and some Wiki information can be found on the main project code page.
UtilitiesFeedback and Contributing
The module pywinusb.hid.tools contains a function to check HID class devices capabilities, for now it provides a basic human readable text report (see the hid.core package, run it as main while HID class devices are connected to your system)
Feel free to contact me! use the main code project page, just tell what do you think about the project or bring me anything you think might be cool to consider.
Any participation it’s appreciated, feel free to contribute more examples or applications or just a reference to your open source project that uses the library.
