But there are some limitations. For generic HID device, it should work. You do need to have libusb-1.0.dll in the system. The other potentially better choice is to use pywinusb if your application is only for Windows. https://pypi.python.org/pypi/pywinusb/ https://github.com/rene-aguirre/pywinusb/wiki/Introduction If you need cross-platform support for your Python application, then pyusb and pywinusb are not good choice for HID device. In that case, you can look at HIDAPI and its Python binding. You do need to have HIDAPI in the system. https://github.com/signal11/hidapi https://github.com/apmorton/pyhidapi https://github.com/gbishop/cython-hidapi -- Xiaofan ------------------------------------------------------------------------------ Transform Data into Opportunity.
