Sorry, I'm still unclear as to which libusb you are referring to -
is it libusb01 or libusb10? (i.e libusb-0.1.x.x. or libusb-1.x.x ?)

e with "--nolibhal", in
any case, the OpenUSB library sample code doesn't work and the tar

I'm not certain that it's the best library for MacOS at this time.

When you say, "debug it" - do you mean libusb01 itself? I can

If we can't identify specific API changes that would change the API I think

As per Jonas' reply, its not clear libusb has been installed. zadig works
for me and makes the install process much easier (if you want super easy,
go with Linux)
I did have some notes on this but they were in Bitbucket and didn't survive
their mercurial purge and I've not found hosting so here is
TL;DR I would recommend AGAINST using pyusb for HID use cases, if you are
on Linux instead use udev.
If you need to know the device that was used to read, I would create a
virtual device id if you really want to read directly from pyusb.. BUT I
would recommend against it.
I've not had to deal wit
