libusb 1.0 is loading from here 'C:\openocd-0.7.0\bin\libusb-1.0.dll'. To use libusb-win32, you either have to remove this file or force the backend. > > The error code is same "[Errno 2] Entity not found" however, pyUsb seems to > be using the libusb1 backend now. > > I don't really understand whats going on here.

I suspect your C# code worked because in C# you were using libusb-win32, and that's because I asked you to give libusb-win32 a try. -- Best Regards, Wander Lairson Costa ------------------------------------------------------------------------------ October Webinars: Code for Performance Free Intel webinars can help you accelerate application performance.
