global for PlatformIO … I not use “tool” exe
With Python libraries using libusb I had good luck putting the libusb dll in the same folder as the python interpeter executing PlatformIO. So, ~/.platformio/penv/bin/.

I have some problem when I test this package on win64.
File "C:\Python27\lib\… site-packages\libusb1.py", line 195, in <module>
libusb = _loadLibrary()
File "C:\Python27\lib\site-packages\libusb1.py", line 166, in _loadLibrary

File "C:\Python27\lib\ctypes__init__.py", line 365, in **init**
self._handle = _dlopen(self._name, mode)
WindowsError: [Error 126] The specified module could not be found
then I download the binary for windows from http://libusb.info/
but I have no idea which file I should use and where I could put the dll file.
Could anyone help me, please

my mistake … I remove Python path from env[‘ENV’][‘PATH’]
DLL together with .platformio/penv/Scripts/python.exe … work
If you can add arbitrary paths to the PATH, then the libusb dll can also be anywhere, not specifically in the interpreter folder.
