from this thread about my first bitbang https://discord.com/channels/967863521511608370/1146821147644657734/1232405118737973300
and with ref to https://discord.com/channels/967863521511608370/1146821147644657734/1197569602952106085

it was not obvious where libusb0.dll was supposed to be present or which distribution of it was needed. it turned out installing Zadig was the solution https://zadig.akeo.ie/

could this highlighted be put in place to save others some time? or some other pre-req check
