PyUSB ValueError: No backend available

Question

I am runing Python 2.7.8 at Win 7 operation system. I am trying to communicate a USB device (Numato 32 channel GPIO device) by PyUSB.

I downloaded walac-pyusb-7071a

Answer 1

I did: - Download and install libusb-win32-devel-filter-1.2.6.0.exe. It should work.

From:

Pyusb on windows - no backend available

And really works for me.
