Hi!
I just tried to run this on Win10 after following the install instructions and I get the following error:

libusb version is 1.0.24 (https://sourceforge.net/projects/libusb/files/libusb-1.0/libusb-1.0.24/libusb-1.0.24.7z/download)
I copied:

libusb-1.0.24\MinGW32\dll\libusb-1.0.dll -> Windows\SysWOW64

libusb-1.0.24\MinGW64\dll\libusb-1.0.lib -> Miniconda3\Library\lib

python is 3.9.5 with the following packages:
