+Hi Gregory,
+We do not yet offer Python as an officially supported language (that is, a language for which we provide working sample programs for the majority of our products).
+However, we are in the process of adding Python to our list of supported languages.
+You can grab a ctypes wrapper for the Windows AIOUSB.dll here: https://accesio.com/files/AIOUSB.py
+There will be minor edits necessary to this file; specifically, make sure the DLL is being loaded from a valid location.
+If you run into any issues just let me know and I'll provide what assistance I can.
+Sincerely,

+Hi Gregory,
+AIO_Init(), and libusb itself, are not used in Windows.
+Our Windows API Library (AIOUSB.dll) doesn't support libusb, and instead uses CyUSB.sys (or CyUSB3.sys) as its driver component.

+Dear John,
+Many thanks for you message. I very much appreciate your quick response.
+The AIOUSB.py sample file you linked will be very useful. Two questions
+. Is AIO_Init() still necessary? I see it is not wrapped.
+. Do you have any thoughts about whether it will be possible to get
+/
+work with an initialised lib_usb handle on the python side? In the
+past
+reusing handles make things run much faster.
+Thank you again,
+Greg.
