Re: [pyusb-users] pyusb1 picks wrong driver on Windows. Asking for help

Your real problem is that you don't know beforehand which driver your device will be using. If you're doing the driver install as part of an installer (e.g. using wdi-simple.exe) or instructing your users to use zadig.exe then you should already know which driver has been installed. I would

Re: [pyusb-users] pyusb1 picks wrong driver on Windows

Hi, PyUSB relies on ctypes for finding libraries, which relies on Windows library search policy, if it finds libusb1 first, then that's what it assumes as the backend. backend parameter was designed for cases like yours, when the default backend discovery policy doesn't apply. Anyway, you code
