I'm using the libusb1.2.4.9 win32 backend I think. I downloaded the .zip file found here: https://sourceforge.net/projects/libusb-win32/files/libusb-win32-snapshots/20110713/ In the zip were the following files: libusb-win32-devel-filter-1.2.4.9.exe libusb-win32-src-1.2.4.9.zip libusb-win32-bin-1.2.4.9.zip libusb-win32-debug-1.2.4.9.zip I did nothing more than run the exe. I feel like I'm missing a step here. ________________________________ From: chris clark <cl...@gm...> To: greg yurikov <gyu...@ya...>; pyu...@li...

Can I just redirect this to another python module that actually implements this? It looks like the generic device code is being fired, not the backend implemention code. Which backend is being used? |
