Windows requires a specific libusb backend installation. not tested) but some users have reported successful installations. Windows is not officially supported (i.e. dll files in it.Īlso, running this code from the adafruit directions has the same "no back end available" error when creating devĬode: Select all | TOGGLE FULL SIZE import usbĭev = (idVendor=0x0403, idProduct=0圆014)
Also, in the adafruit docs its says to download a new libusb file from sourceforge and copy some. I have switched to the libusb-win32 in zadig like mentioned in other threads but it still did not work. I still get the no backend available issues. Going back to python 3.8 solved that though.Ĭode: Select all | TOGGLE FULL SIZE from pyftdi.ftdi import FtdiĬode: Select all | TOGGLE FULL SIZE Ftdi.show_devices() I uninstalled and reinstalled setuptools, pip, and python multiple times. t couldn't find setuptools while installing. One issue is that setuptools wouldnt work with the different version of pyusb (from the install guide) on python 3.9. I have it all installed like the adafruit directions state. I have been fighting the FT232H and I've not made much progress.
