Hello everyone!

I suggest you stock up

on DBIbackend and I get an error when trying to create a server.

The file "/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages/usb/core.py", line 1263, in find

raise NoBackendError('No backend available')

usb.core.NoBackendError: No backend available

libusb and pyusb are installed

MacBook Air, macOS 26.1

Wht is the context here? Stock up?

Are you using the Python download from Python.org, configured as your default Python?

Or are you (trying to) using an Apple-provided Python? Or trying to use Homebrew?
