WinUsb_Initialize 总是得到 0 和错误 31

Question

本人使用python，参考以下网址修改代码 https://github.com/thesacredmoocow/g14control-r2/blob/cc8064b38dbddca551f0301a254b578c508122f5/winusbpy/examples/winusbtest2.py

但是我打印这段代码总是得到 0 结果并得到错误 31 我做错了什么

result = api.exec_function_winusb("WinUsb_Initialize", handle_file, byref(handle_winusb))
